Can you check if this happens with 5.18 as well? If so, try to capture the panic message.

The situation with the bug on 5.18 has not changed. As before, the system goes
into the panic kernel...

Although I just had on the AMD FX-6300 virtual machines seemed to work under
the 5.18 kernel on the host. It looks like this is some kind of bug that only
appears on AMD Phenom X4.

I'm getting the exact same error on 5.17.9 and 5.18 too. The only difference is
the hardware:
[ 32.571294] Hardware name: Hewlett-Packard HP Z600 Workstation/0AE8h, BIOS
786G4 v03.61 03/05/2018
with this processor: Intel(R) Xeon(R) CPU X5550

Who has a source based kernel, you can apply this patch:
