Bug#1036644: linux-image-6.1.0-9-amd64: System crashes. Netconsole reports CPUs not responding to MCE broadcast

[kolafl...@kolahilft.de]

I was able to resolve the issue with my ASRock J4105-ITX board (Celeron J4105) on Debian-12. I just had to

  apt install intel-microcode



Without that intel-microcode package
  /sys/devices/system/cpu/cpu*/microcode/version
is 0x26 (38 decimal).
And with intel-microcode-3.20230512.1 the version is 0x3e (decimal 62).

(haven't updated to BIOS 1.60 yet)


Kind regards,

and reboot. After 4 weeks of running the system 23/7 I had no further crashes. I'm not sure why intel-microcode was not installed by default. All my other Debian computers have that package installed automatically. I had some very rare crashes with Debian-11. So Debian-12 maybe just worsened the issue and it already existed before updating to Debian-12. In theory a BIOS update might also do the job. I run BIOS 1.40 and there is a 1.60 version from 2021. But 1.60 does not list a microcode update.
