I guess it just escapes me why someone would even *want* to use the
non-BusLogic driver with a BusLogic board, when a BusLogic-specific
driver exists! The reasoning fails to make its way through my
brain...
You have a BusLogic card -- use the BusLogic driver! How hard is
that?...

I've also heard that the fault is not with the SCSI controller, but
with the VLB circuitry. Some VLB slots do bus-mastering rather quite
poorly. Maybe it's your motherboard that's causing you so much pain.
Have you tried moving it to a different slot? It may be that you have
one master slot and all the rest are slaves (or maybe no true
mastering slot at all... ack :-P ).
