Have not seen this again on the G5 7,2 since kernel 5.2.x, nor 5.3.x.
Will close the bug for now and hopefully it does not return. ;)

Mkay... seems I was only lucky with my top-notch G5 hardware not having seen
this bug for quite some time.
Re-opening 'cause this is already the 2nd report this bug (still) affects other
hardware.

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.

I experienced this problem today, a freeze on an
processor : 3
vendor_id : AuthenticAMD
cpu family : 22
model : 48
model name : AMD GX-412TC SOC
on Debian 10 4.19.0-11-amd64 #1 SMP Debian 4.19.146-1 (2020-09-17) x86_64
GNU/Linux
with more and more sysrq messages coming up resulting in the following syslog
entry
Oct 15 11:43:45 gate kernel: [1545118.045973] rcu: INFO: rcu_sched detected
stalls on CPUs/tasks:
leading to the system becoming unreachable. Only after a reboot this works
again.
