I ran into a similar type of problem on an old Compaq DL360. It hung
on any attempt to halt, and required a power cycle to clear. I did track
it down to the 1.113 revision of sys/dev/pci/pci.c, which disables bus
master accesses. You might try to comment out the code in
pci_child_shutdown() and see if that also makes it work. If I ever get
around to getting my PWS500au connected back up, I could also check this,
but I'm getting deep into the SMP problem at the moment.
