Computer randomly restarted

Ask Fedora

Hello… This is the second time happening.
Been using fedora 41 on a Thinkpad T16 gen 1 for 3 weeks, no issues all perfect.

So a couple of days ago while I was using the laptop it randomly restarted, no warning at all, I was watching a yt video and the computer just restarted. Never happened before. I thought it was because of over heating, since it was plugged in charging and on top of my bed, so maybe no air was flowing.

Now it happened again, like 5 minutes ago. But now the pc is in clamshell mode, connected to external display, and it’s on top of a laptop stand that keeps the laptop in perfect conditions for ventilation. I don’t understand why this happened. The laptop is connected to the power supply and it was not overworking, just some light python coding.

Help? I don’t even know what other info to share.

The most likely cause is usually a crashing GPU driver. There is probably some information to be found in the system log, you can issue the following command in a terminal window:

$ journalctl -b -1 -p 3

Explanation: the -b -1 parameter indicates you want to look at the previous boot, if you want to see two boots back you would use -2. The -p 3 parameter indicates you want to see all the lines with the level ‘error’ or higher.

Here is the output if you can make sense of it. output crash - Pastebin Service
Thank’s

Woo!!! It just happened again!!! It happened at 20:35. Here’s an updated run of the previous command: updated

Hmm there are a few odd crashes visible, but there isn’t a clear indication of the cause.

Is your system fully up to date otherwise?

The most likely causes at this stage would maybe be a kernel bug, a mismatch between system libraries, or a hardware error (in order of likelihood).

I updated a couple of days ago. These are the outdated packages:

Now updating… Will see if it happens again.
Currently running:

Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.1
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.12.15-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 16 × 12th Gen Intel® Core™ i7-1260P
Memory: 31.0 GiB of RAM
Graphics Processor: Mesa Intel® Iris® Xe Graphics
Manufacturer: LENOVO
Product Name: 21BV00AVIX
System Version: ThinkPad T16 Gen 1

Mesa can potentially cause nasty crashes if it doesn’t work well, but it’s hard to say if that is the cause.

Do you maybe have the option to boot into an older kernel to see if that improves the situation?

Yes, I have access to older kernels that fedora installed previously. If another crash happen I’ll pass to lower kernel, if it crashes also there, I’ll write back here.

It happened again!!! Here’s the command run: new - Pastebin Service

Now, I selected another kernel version:

Operating System: Fedora Linux 41
KDE Plasma Version: 6.3.1
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.12.13-200.fc41.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 16 × 12th Gen Intel® Core™ i7-1260P
Memory: 31.0 GiB of RAM
Graphics Processor: Mesa Intel® Iris® Xe Graphics
Manufacturer: LENOVO
Product Name: 21BV00AVIX
System Version: ThinkPad T16 Gen 1

Let’s see…

Maybe it’s just a coincidence… but so far this has happened only when watching a yt video while coding (I’m coding some really basic stuff in python on vs code). So far I watched lots of yt videos with no problem, but all the times it crashed when I was watching a video with vs code opened… Most likely it’s just a coincidence…

You could perhaps try disabling hardware acceleration in Brave for a bit to see if that makes a difference?

Not using brave. I just installed it but I’m not using it nor have any window of brave opened.

13

Oh, how are you watching Youtube in that case?

14

I do everything on Firefox

15

Ah then you could disable hardware acceleration there:

Ok. I’ll wait for another crash, in order to see if the problem was the kernel. If another crash happens I’ll try that and report back.

17

@litemotiv … It happened again: Output - Pastebin.com

So it shouldn’t be a kernel problem… Now I disable hardware acceleration on firefox as per your suggestion and let’s see.

Hello, so yeah this is the problem. Since I tweaked that settings no more crashes. Today I migrated to LibreWolf (a fork of Firefox) and got my first crash while watching a video.

I’ll mark this as solved and thank’s for your good help.

Is there something I can do to make sure this gets fixed?

It’s unfortunate but there is probably not much you can do except wait until they fix this upstream. You can take a look at the bug trackers for intel and mesa, it’s likely that there are existing tickets about this that you could follow to keep an eye on progress:
