I know this is old but I have been having some issues for a while, I was
finally able to get something useful:

This happened just after freshclam ran but I don't know if it's related.
This is with a Ryzen 7 1800X CPU.
5.4.0-48-generic #52-Ubuntu
I thought I had sysrq configured but it seems not so I can't really provide any
more information, other than this is driving me crazy.
