kernel panic on warn message

Hi,

After a few hours/minutes/days (incredibly random) one of my servers keeps crashing (panic_on_warn is enabled for security purposes.)

I have tried adding `acpi=off` `pcie_aspm=off` and `nowatchdog` to the kernel params but nothing solves it for good. I disabled SMP in the BIOS as well, CPU is an AMD Athlon II X2 B28.

Panic trace attached, server is a minimal Slackware system, nothing fancy. This problem just started happening recently, server has been up for the past year with no issue.

Same problem occurs on kernel version 5.4.20 as well.

Thanks!

Alec
