hello all, had unraid reboot on me randomly today. i have a script that copies the log to another location every 5 minutes, didn't see anything in there. when it came back online, Fix Common Problems reported an issue:

 

Your server has detected hardware errors. You should install mcelog via the NerdPack plugin, post your diagnostics and ask for assistance on the unRaid forums. The output of mcelog (if installed) has been logged.

 

I didn't have mcelog installed, so I installed it. But I guess this only logs going forward? In any case, in my logs from after the reboot (before mcelog was installed) showed the following message:

Is the zenstates fix still required for 6.7? I have my C-states in BIOS disabled already.

If that's the only MCE listed period, then don't worry about it.  Happens with certain hardware combinations when the OS initializes the CPUs
