I have a couple BP6's running -stable and was having hard lock problems
under heavy IO until I dropped back to ATA33 on the drives (I moved them
to the onboard Intel controller instead of the HPT366).  sos@ informed me
that the HPT366 has a buggy DMA controller and that ATA66 on them wouldn't
work.  After moving to ATA33 in early 2001, I haven't had any more hard
locks.  This was under -stable, but you might want to check your ATA drive
setup before proceeding.
