Re: Segfaults after upgrade to Debian 11.7 on virtualized systems with AMD Ryzen CPU



Hi!

A follow-up, because after reading my previous mail again I think
I should clarify one thing...

The Debian 11.7 VMs crash only when the system is booted with
the current Debian 11.7 kernel (5.10.0-22 i.e. Linux 5.10.178-3
from 2023-04-22) and initrd created when upgrading to 11.7.

When I select the previous entry in the boot menu (kernel 5.10.0-21,
Linux 5.10.162-1 from 2023-01-21 and initrd for this kernel) the
same system boots fine and is perfectly usable.

Any ideas anyone?
