Well, serial console is a little complicated due to the lack of any serial
port.
 An USB-to-serial adapter didn't work as I couldn't get a remote connection
working.

Anyways; crashes are still there. They range from sudden black screen (fans are
still running, any music that played before just stopped) to hard system
resets.

Latest beta BIOS (with AGESA 1.0.0.6) is applied. Tried several BIOS settings
regarding LLC, downclocking, disabling SMT, increasing SoC or CPU voltage. No
improvement.

Yesterday, I've gotten a new mainboard (ASRock AB350 Pro4). And it crashes
there too with black screens. Disabling "OPCache" in the BIOS (as suggested in
the AMD forum's thread) doesn't help.

I'm really out of ideas here...
