I don't know if it's the right place to ask this, don't hesitate to tell me if this isn't the case

Starting from today, Slack randomly crashes and freezes my computer, forcing me to force reboot. I managed to extract this log from /var/log/syslog :

Feb 27 08:56:53 pc-de-jeremy kernel: [  794.539163] amdgpu 0000:05:00.0: amdgpu: [mmhub0] no-retry page fault (src_id:0 ring:40 vmid:1 pasid:32777, for process slack pid 6335 thread slack:cs0 pid 6376)

Whenever a crash happens and I don't reboot immediately, I get a lot of this error.

I found some issues about some error looking a lot like mine, like this one : https://gitlab.freedesktop.org/drm/amd/-/issues/2113, but I didn't find a solution yet.

Last time I used Slack was about 2 weeks ago and it worked fine

I tried to update every upgradable package (including amd-related drivers), no luck

Thanks for your time and help !

Alright, I still don't know what the issue was, but it was fixed in the version 6.1 of the Linux Kernel. I updated it and the error hasn't happened since. Unfortunately it seems that Ubuntu does not let you update the Kernel without updating the OS itself. You can upgrade from mainline with the following commands :

sudo apt-get install linux-headers-6.1.0-1006-oem \
    linux-image-6.1.0-1006-oem \
    linux-modules-6.1.0-1006-oem \
    linux-tools-6.1.0-1006-oem

I think the mainline channel isn't as well tested as the official channels, so use at your own risk. Though, on my end, it fixed the issue and did not cause any others.
