I have Debian 12 on one computer and Debian 12 and 13 on another. The
first one is an old backup I rarely use. The new one was crashing in both
Debian 12 and 13 so I sent the MB back to MSI. I started using the backup
computer and it's crashing too, so MSI will probably send the MB back and
ask "Why did you send this to us? There's nothing wrong with it."
I usually run with an XTerm window, Evolution, Firefox, and occasional
NEdit or Okular windows. The entire system (not just one app) was
crashing, usually when I was reading mail and then reading stuff linked
in mail messages using Firefox 128.13.0esr. I think Evolution wasn't to
blame because I started having it not running, opening it only
occasionally, and I got a crash while Firefox was running. By "crash"
I mean that the mouse cursor stops working, the graphs in GKrellM stop
moving, Alt-Ctrl-F12 doesn't switch, Alt-Ctrl-Del doesn't do anything,
tapping the power button doesn't offer me a "what do you want to do"
overlay, ….
Hello, on Debian 12 I have seen the same lockup symptoms that you describe
that seem to be related to Firefox 128.13.0esr, and I have found it seems
to not occur if I disable the "Use hardware acceleration when available"
setting in Firefox.
It crashed with two different graphics cards, NVidia K2200 and AMD Radeon RX580.
In my case, I suspect that this might be because my older graphics card
(AMD "OLAND") is slightly unsupported by the available driver, at least
that is how I understand this message in the kernel log:
kfd kfd: amdgpu: OLAND not supported in kfd
In some situations I see possible indications of this, for example when
mousing over the timeline on a youtube video, Firefox renders the video
thumbnail preview as just a pattern of lines, which is suggestive of a
direct memory access problem. Which of course is not a good thing.
When the lockup occurs, I guess that is because the graphics hardware is
scrambled and needs reset. It is possible to ssh into the machine when it
is locked up, and everything except X-Window graphics seems to be running
ok. And the only way I have found to reset the graphics hardware is
a hardware reboot. But I'm pretty clueless about display graphics, if
anyone knows a better way or has other advice.
The first few times it occurred I couldn't ssh to the computer. I didn't try to do it every time. The keyboard and power button were also frozen.
