My Fedora 40 system won't boot with any kernel over 6.8.10.

I've had this problem for about a month now and have been putting it off, as I haven't really been using my computer recently, but it needs to be addressed.

I'm running a Fedora 40 KDE 6 distro, which was upgraded from Fedora 39. It's been working pretty well for the half year I've been using it but recently I've encountered an issue. About a month ago, after upgrading my system to kernel 6.8.10, my system started to hang while in boot.

usb 1-10 device descriptor read/64, error -71 [ OK ] Started plymouth-start.service - Show Plymouth Boot Screen [ OK ] Started systemd-ask-password-plymoūquests to Plymouth Directory Watch [ OK ] Reached target paths.target - Path Units. [ OK ] Found device dev-disk-by\x2duuid-dūsung SSD 970 EVO Plus 500GB fedora. [ OK ] Reached target initrd-root-device.target - Initrd Root Device. [ *** ] Job dev-mapper-cl\x2dswap.device/start running (xxs / no limit)

Fortunately Fedora saves the previous 2 kernels versions and I was able to boot into my computer using Kernel 6.8.9. When I went to check what was wrong I noticed that with kernel 6.8.10 it always hangs at this part of the boot process.

[ *** ] Job dev-mapper-cl\x2dswap.device/start running (xxs / no limit)

I understood that this has something to do with swap but I'm unsure what the issue is exactly. My Fedora install doesn't have a swap partition, it uses zram. I'm unsure if that's an issue.

I've reinstalled kernel 6.8.10 and it didn't fix the issue. I've also upgraded my machine to use kernel 6.8.11 and see if that would fix anything, but it did nothing, and upgrading to 6.8.12 probably won't fix anything either. I've installed a dnf plugin called versionlock meant to pin certain kernels as to not delete them and have already pinned kernel 6.8.9, but I'd still rather avoid upgrading.

What I really don't understand is what changed. Why does my system boot successfully in kernel 6.8.9 but fails in 6.8.10. I've read that others have had a similar experience with the 6.8.10 kernel on fedora, albeit for different reasons.

If someone can point me to the answers that would be great, but an explanation as to how to read that log and steps I could take to identify and troubleshoot would be just as welcomed.

My Linux Mint Cinnamon won't boot up. It's getting stuck on this screen and I don't know what to do to proceed. Before this screen appears it shows the LM logo for a moment.

I'm a total noob and just been using this for a month or two. Did not make any recent changes that I can recall.

I need a few of these for rpi's around the farm. Tired of dealing with LoRa.

I'm running a few Debian stable systems that are up to date on patches.

But I just ran ssh -V and the OpenSSH version listed is "OpenSSH_9.2p1 Debian-2+deb12u3" which as I understand is still vulnerable.

Am I missing something or am I good?

I have a UVC capture card that I use to play my Switch. Currently, I utilize it via the full screen projector feature of OBS, but the Switch is 1080p while my monitor is 4k and the upscaling that OBS uses causes some noticeable artifacts.

I’m wondering if there’s an application with some configurable upscaling options that would make this experience better. I don’t need anything crazy that would cause noticeable input lag, but anything even slightly better than OBS would be welcome

Hello. I recently created a notification daemon which uses eww widgets for its front-end display. So if you are already using eww, give it a go.

I know this is a very niche use case, but if a single person finds it useful, I will be glad.

Hello everyone,

I'm looking to increase the security of my computers a bit through firewalld (with the KDE settings). I have a desktop and a laptop, both running Fedora 40 with KDE plasma. I don't have access to the router's firewalls etc etc this is only for my machines.

The issue is I'm having a hard time navigating the zones and setting rules the way I want. I don't wanna deal with switching to UFW and while I generally like CLI stuff I'd prefer to generally stick with the GUI here even though I find it a bit confusing (I will use CLI if necessary tho).

Anyways, let's get to the point. Firstly the only difference between the laptop and desktop, in terms of use-case, is that on my desktop I'm always connected to my home's subnet via LAN while on my laptop I often connect to public wifis, so naturally the laptop is a little less secure.

For my use-case I care about 3 network interfaces:

• tailscale: this is the one I use to ssh into my machines and stuff and I want this to be the only interface which allows me to ssh. This is because not only it allows me to ssh remotely but also I figure is also the most secure way to use ssh as the tailscales team is probably better at security than I am.
• Proton VPN's: this I use for gaming, web browsing and seeding Linux ISOs so I'd like settings that block everything without affecting these usecases.
• normal internet: I almost always have my VPN on but occasionally I don't for one reason or another and I only use this for web browsing and gaming via steam. Settings I'd like here are essentially the same as ProtonVPN's but stricter if it makes sense to be stricter, especially on the laptop where it's likely a public wifi I'm conencting to when I'm not home. If it's possible I'd also like this interface to be hidden from nmap scans.

I do some light pentesting to learn so there's also that.

I currently have every relevant connection set to FedoraWorkstation zone by default except I manually tell the laptop to switch to public zone for public wifis (I'd change the default to be public and specify other zones for non-public connections but rn I'm in a period of time when I'm only connecting it to my home network so I wanna figure out this out first).

My question is, which zones should I use and what rules should I implement to make this more secure?

Thanks in advance

For example, there is Material Notes which has a editor toolbar with bold, indented, ~~stroke~~, etc. But this is rendered, exported to json or syntax like Markdown. This app too, in which i write this on lemmy, does the same. We have ☐, ☒, •, ‣ in Unicode, 𝗕𝗼𝗹𝗱, 𝑖𝑛𝑑𝑒𝑛𝑡, s̵t̵r̵o̵k̵e̵, so why not use this?

Basically, what i'm looking for is a text editor with toolbar/keystrokes for Android or Linux, which adds unicode symbols for rich text. It would make reading plain text notes/todo lists cross-device simpler. Yes, there's UnicodePad and Charmap but that's not the same.

edit: something where you mark a word, tap the B in the toolbar or press ctrl+b and it replaces the characters with uc bold characters, no? Tap the list button and it adds uc bullet points, etc...

So which one is actually official one? I can't describe what "official" mean here, maybe the one that actually came from reddit or the one with more subsscribers or one with more activity ?

Also Why there are multiple copies of same community in different instances? Isn't the whole point of lemmy is that it is federated?

It peaked at 4.05% in March. The last 2 months it went just below 4% as the Unknown category increased. For June the reverse happened, so 4.04% seems to be the real current share of Linux on Desktop as desktop clients were read properly/werent spoofed.

Hi ! I'm a little confuse between all immutable versions based on fedora. Is this correct : universal blue = tool to create image, based on fedora atomic desktop ?

With universal blue, they created :

• Bluefin = gnome
• Bluefin-DX = gnome + developper tools
• Aurora = kde
• Aurora-DX = kde + developper tools
• Bazzite = games

What the difference between silverble and bluefin for example, and which are you using ?

Can I delete previous backups, without affecting following backups, Since TimeShift (RSync) make increamental backups.

i'm picasso.

I have been using a company computer running Ubuntu 22.04. There are frequent and unexplained problems, like segmentation faults, stack errors, files disappearing, computer freezing or not booting, or turning off immediately after I turn it on. I don't know what to do. The IT staff came to my office to check the computer and said "it was all good." I am not allowed to boot from a USB stick or enter BIOS or open the case. I ran a command line memory check several times with no errors. There is an NVIDIA card, but it's running X.org and usually headless. I mostly set up tasks via SSH.

What would you do?

Hello! My disk space was out of space left, so I decided to remove some snapper snapshot. snapper list listed over 360 snapshots. I removed them, and freed 50Gb of space. One of these hasn't been deleted successfully:

Cannot delete snapshot 166 since it is the next to be mounted snapshot.

it's description is writable copy of #156. How can I remove it? should I do it using btrfs subvolume delete?

here's the output of sudo btrfs subvolume list -t /:

all those timeshift subvolumes are there because before snapper, I used to use timeshift. I tried to remove them:

sudo btrfs subvolume delete timeshift-btrfs/snapshots/2023-09-18_18-25-33/@/var/lib/machines

If I understand correctly, it means that I should give an actual "system" path instead of the path in the table, but I don't understand which path

thanks in advance to everyone!

i recently switched to connman and i need a tui. so i searched for some and got:

• connman-ncurses
• cmtui

but i believe both are orphaned. so it there any tui for connman out there?

I'm working on my transition plan away from Windows and testing out various things in VMs as I do so, and one big hurdle is making sure the VPN client my work requires can connect. Bazzite is my target distro (primarily gaming, work less frequently), though other more traditionally structured ones like Pop!_OS and Garuda are possibilities.

I'm currently trying and failing to get the VPN client working in a distrobox (throws an error during connection saying PPP isn't installed or supported by the kernel). However, I can successfully get the VPN connected if I overlay the client and its dependencies via rpm-ostree install, but I read somewhere that Bazzite's philosophy is to use rpm-ostree as sparingly as possible for installing software to preserve as much containerization as possible.

Since I can get it working outside of a container, am I overthinking it? Should I just accept that this might be one of the "sparing" cases? Is Bazzite perhaps a poor fit for my use case? I've been trying to make sense of this guide, but I'm having trouble understanding how to apply it to my situation, since I'm not that familiar with Docker or Podman.

First, before this rather large infodump, I want to thank anyone that takes the time to read through this to offer any information or advice on trying to resolve this issue.

Here’s the issue I’ve been struggling with.

I keep getting this error on my server:

INFO: task txg_sync:1615 blocked for more than 241 seconds.
Tainted: P           O      5.15.0-112-generic #122-Ubuntu

Background:

I’ve got a homeserver running Ubuntu server 22.04 (no DE) with an Intel Core i7-6700K CPU @ 4.00GHz, 32GB RAM, and two ZFS pools. The OS is installed on its own 128GB SSD, and the two ZFS pools consist of a 128GB SSD in its own pool for the server’s cache, and a 4x8TB HDD RAIDZ1 pool that is my main data/server storage (much more detailed system info below).

I have a bunch of services running in Docker containers, and overall everything is great, except for when that error rears up.

The error seems random, but occurs most reliably, but not consistently, when I’m trying to write larger media files to the RAIDZ1 pool. I am aware that this an IOPS issue, but so far I have not been able to diagnose it.

Back in February, I was carrying some boxes down to the basement where the server rack is, and I accidentally kicked a stool into the server which knocked the shit out of it (it’s a tower pc that I built back in 2016 or 2017 and repurposed in 2020ish to server use). When I turned on the monitor it was in total panic mode. The screen was gibberish colors and flickering madness.

I had to force shutdown with the power button. I waited a good couple of minutes, and on reboot, everything seemed fine. Until I noticed the new txg_sync error a week or so later when I went down to add some media to the server.

After a lot of searching and reading that didn’t turn up pertinent info, I ran across a comment that said this error is almost always hardware related. Like a loose connection or a failing disk or something. With me having knocked the shit out of the server, I realized I should have opened the case up and checked it all out. I shut it down, opened it up, and found a loose connector on the motherboard. I reseated it, checked everything else (though not thoroughly enough, which we’ll get to), and rebooted hoping I had found the problem.

It seemed fine for a bit, but no luck. The error returned.

More searching with no luck, and then about a month ago, a friend he suggested I check all the SATA connectors by disconnecting each one and reconnecting to insure a good, solid connection. I had previously checked if they were seated when I opened the case, but didn’t disconnect and reconnect. While doing this, I found a SATA cable with a busted clip and thought again I had found the problem. I replaced the cable, and went about a week before the error resurfaced.

It continues to occur, as I mentioned inconsistently. Most reliably, but not always, when writing data to the RAIDZ1 pool.

I have run a thorough memtest, and there were no errors or issue with the RAM, and as far as I can tell, there are no errors/failures with the HDDs.

Below is a lot of system info, and an example of what I find in dmesg for the error.
