Description Eric Benton 2024-07-25 04:22:58 UTC

I have 2 laptops - one is an 
   ASUS ZenBook UX535LI_UX535LI
the other is :
   MSI Katana GF66 11UE

At random times I get kernel crashes, but mostly on reboot while its shutting down.
I installed the debug kernel on the ASUS along with kdump and cockpit hoping to get more detailed information but, of course, then it wont crash.
This doesn't happen every reboot, but it's often enough to be annoying and its happening across multiple kernels. Occasionally, I get a crash while I am surfing the web or just moving the mouse.
ok, why do i think its a kernel crash? Because the system hangs and the caps lock led flashes on & off rapidly for about 90 seconds and then the laptop resets. Am I right that this indicates a kernel crash?
Not sure where to go from here.

Likely.

Have you enabled kdump at all? As it looks like it didn't trigger kdump, given blinking leds and reboot after 90 s.

systemctl statud kdump will tell you.

Also you need to set crashkernel kernel parameter.

Yes, I have tried kdump but when i switch to the debug kernel the crash hasn't happened.

Comment 4 Jiri Slaby 2024-07-26 10:59:28 UTC

So I would recommend to go back to -default and setup kdump. So that we can move   forward.

Comment 5 Eric Benton 2024-07-26 12:22:30 UTC

I thought kdump required a debug kernel?
