Hey John,

I just got some time to try out the latest lock patch. I also updated to
stable/13-n255040-535fc5f75e20 as well.

Using the lock patch, the system didn't crash at boot up and we got some nice
messages:

hdac2: <AMD Raven HDA Controller> mem 0xfc980000-0xfc987fff at device 0.6 on
pci19
hdac2: Unexpected unsolicited response from address 0: 00000000
...
pcib20: <ACPI PCI-PCI bridge>hdac2: Unexpected unsolicited response from
address 0: 00000000
...
hdac2: Unexpected unsolicited response from address 0: 00000000
 at device 8.3 on pci0
pci20: <ACPI PCI bus> on pcib20
xhci4: <XHCI (generic) USB 3.0 controller> mem 0xfcd00000-0xfcdfffff at device
0.0 on pci20
...

When in this state the system starts up without crashing, but the audio device
is missing (which makes sense). Once I do another reboot (hot start), no more
error messages show up and the audio devices are available.

I've attached the hot/cold.txt labeled with "2023-04-09-2125".

Thank you!

Jonathan
