The two machines running netbsd-2 ATM are 32bit pci boards. They 
sort-of-work under light load with the occasional panic during the 
daily cron jobs. Moving the disks to the two newer machines (64bit 
pci) makes NetBSD jam while booting to multi-user. Using the older 
controllers (all are 64bit pci cards) makes no difference.

So both machine generations have the mpt problem, only it hits much 
worse/earlier with the 64bit pci boards.
