Hi,

I have AMD Ryzen 3 2200G and Debian 9.

uname -r

>> 4.9.0-6-amd64

From time to time there appears an odd error:

"Message from syslogd@debian at Jun  5 17:24:55 ...

kernel:[11096.370599] Uhhuh. NMI received for unknown reason 21 on CPU 2.

 

 

Message from syslogd@debian at Jun  5 17:24:55 ...

kernel:[11096.370603] Do you have a strange power saving mode enabled?

 

 

Message from syslogd@debian at Jun  5 17:24:55 ...

kernel:[11096.370605] Dazed and confused, but trying to continue"

 

The system keeps working without a problem but I'm worried. The reason is always 21 and the core is always number 2. Is it some small Linux kernel bug or something is wrong with my new CPU?

 

P.S. I don't have a strange power saving mode enabled
