My point was not to say that the driver isn't incidentally buggy, but if
there are termination or cabling problems, then it's not the bugginess of
the driver that's the problem. If fixing the term & cabling fixes the
errors, then there's no way of even knowing that the original problem WAS
the error that was reported (scsi protocol errors in manuel's case), since
it was likely spurious emissions & could've been anything, & didn't have to
be something "not entirely unexpected".

I've heard enough complaints of ncr being buggy that I certainly don't
doubt that it is...I just wouldn't have blamed the driver for the problem
that manuel was complaining about. There's not a driver on the planet that
can't be broken with bad-enough cables & term...that's one of the fun
things with SCSI voodoo :-).
