yes, but you wasn't compiling a generic kernel. You seems to miss a

pseudo-device loop 1

in your kernel configuration.

I would suggest you to update clock.c and mainbus.c in sys/arch/pmax/pmax
to latest version. clock.c to get correct year after reboot and
mainbus.c to make sure that kernels dosn't hang after identifying
mainbus0.

I have no clue why the machine doesn't answer anymore.
