This still happens under 5.2-RC, but I have a little more information.

The problem is that when ACPI is in use, the normal keyboard controller 
based reset procedure doesn't work, so it says it's going to try a CPU 
reset. That causes a double fault and things go downhill.

Alas, booting with ACPI disabled aparently hoses the interrupt routing 
so that I get no network I/O and lots of 'fxp0: device timeout' messages.

This machine is really stuck between a rock and a hard place.
