Kernel panic - not syncing

audiolunaire · 2024-03-21 13:37:30

Recently during booting and working my kernel started to panic. I can sometimes launch my system but it takes a lot of forced reboots. I presume that the reason for this is due to the setting in the linux-hardened kernel "PANIC_ON_OOPS", but i still want to try and diagnose the issue. Sadly, I can't find the kernel panic messages either via journalctl -b or journalctl -k so here is a typed out version of the last three lines

"Kernel panic - not syncing: Fatal exception
Kernel Offset: 0x1f000000 from 0x0ffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)
---[ end Kernel panic - not syncing: Fatal exception ]---"

Not a lot of info, so I don't really know what to do. Please help ;-;

For the panic, linking a photo of your output would probably be better.
You're not getting a journal record if you reboot w/ the power button (or the panic occurs very early)

Or maybe does the regular kernel just OOPS (which should be way easier to determine/research)

it probably does (see the PANIC_ON_OOPS setting which is turned on by default in linux-hardened). if it does just oops, how would i go about troubleshooting that?

Looking at it (should be no problem if the kernel still boots), research its cause and mitigate that - if possible (eg. blacklist an offending module, sidestep the issue w/ a relevant parameter or just downgrade the kernel / use the LTS one until the problem is fixed; in doubt raise a bug upstream)
