Hi all,
I am recently experiencing an issue with Debian 12. The system occasionally freezes completely (nothing is responsive, audio stuck in a loop of the last 2 seconds and SysRq does not work) so I am forced to do a hard reset. This happens quite infrequently (maybe every 2-3 weeks) at seemingly random times.
Long story short...the most difficult scenario one could possibly imagine to diagnose.
Now, I do not expect anyone to tell me what is wrong with my system, considering it could be anything from software to harware to configuration to BIOS (I use coreboot) to power issues and so on.
What I hope is that somebody could help me to set up Debian so that when this happens again I can gather as many logs as possible to at least get some clues where to start troubleshooting. Of couse, I already went through the usual /var/log options and journalctl but could not find anything useful. No logs for the time just before the crash event.
Are there any tools that can collect more logs or memory dumps before a crash?
I have read a bit about kdump and kexec, but I am having a hard time understanding how to properly set them up.
Does the capture of kernel memory even work if I have to hard reset the system and cannot reboot?
My system specs are: AMD A8-6500 APU, A88XM-E motherboard, coreboot and 8GB of DDR3 RAM.
I checked the RAM for errors and PSU for voltage outputs, everything seems fine.
