Every weekend I get a notification form Fix Common Problems about mcelog not supporting my processor:

Jan  5 09:52:58 Ragon root: Fix Common Problems: Error: Machine Check Events detected on your server
Jan  5 09:52:58 Ragon root: mcelog: ERROR: AMD Processor family 25: mcelog does not support this processor.  Please use the edac_mce_amd module instead.
Jan  5 09:52:58 Ragon root: CPU is unsupported

 

From looking through the forums, it looks like this can just be ignored, but I just wanted to check if I was missing something important. Also, can I safely ignore the error in Fix Common Problems or is there a better solution?

 

I'm running a AMD Ryzen 5 5600X with a MSI X470 GAMING PLUS MAX (MS-7B79) mobo on Unraid 6.12.14

 

I have the mdac_mce_amd module:

# lsmod | grep edac_mce_amd
edac_mce_amd           36864  0

 

This is what I get from mce in syslog

~# grep -i "mce" /var/log/syslog

I’ve had one MCE on my Ryzen based system recently on a 7beta however if it’s reoccurring you probably should evaluate your hardware.

 

unfortunately with AMD it’s not possible to read the MCE log.
