Severity: important

Dear Maintainer,

quite often, when booting my PC, I get a kernel panic (the computer 
hangs and the caps lock led blinks) at boot time, or just after it ends. 
I suspect this might be related with me typing my password, or moving a 
mouse at an unfortunate time (too early, something still initializing?), 
but I'm not certain that this is it.

Once the system boots successfully and I log in, the kernel panic 
doesn't happen.

For example, today, the kernel panic happened when I submitted my 
password to the GDM login screen. I think I also had it happen while 
entering my LUKS password at least once. Also, the PC actually crashed 
the first time I booted it after installing Trixie, causing me to delay 
trying Trixie out for a couple weeks.

My setup is a Lenovo P15v laptop, which is connected via USB-C to a 
Samsung LS27A600UUU (27" ViewFinity S60UA QHD, USB-C Monitor), to which 
my keyboard and mouse combo are connected via USB-A port, as well as a 
second 27" Samsung display via the DP-OUT port. I suspect that maybe 
this complexity could have something to do with the freezes and be the 
reason why they haven't been noticed and caught until now.

I don't think it's a faulty hardware issue however, because I have used 
Pop!_OS 22.04 for several years now (it still resides on my second SSD 
disk), which *never* exhibited such behavior.

Cheers!

6.12.38-1 is not the most current kernel available in trixie, pliease
do update to 6.12.48-1 and let us please know if the problem persist.

If yes, then we would need (ideally a full) boot log, but if nothing
get recorded in logs, then the netconsole[1] approach might help

[1] https://docs.kernel.org/networking/netconsole.html

On UEFI system pstore alterantively might help us as well.

But first upgrade your kernel to the most current one in trixie, to
determine if the problem persists.

Regards,
Salvatore

Hi,

disregard the original subject line, I actually upgraded to 6.12.48 this 
morning and reported the bug with that kernel already in use, as 
indicated in the System Information block.

I'll see about the logs. I don't tend to reboot often, and when I 
checked with `journalctl -b-1` (and other numbers) today, I didn't see 
anything weird at the end of these logs: they all indicated successful 
logouts. I suspect they aren't being saved for some reason. I'll look at 
them again the next time Trixie crashes on boot.

Regards,
Rimas

Thanks, I have updated the metadata.

Okay let's see if we can get further information on the crashes.
