    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.
