HELP!!

I'm now trying it on an A4000 with a rev 11 Buster. The FastLane is set to
'slow' mode. I've improved the cabling, removed a suspect drive and still
cannot boot into multiuser mode without getting a 'buss-error' panic crash at
the end of the boot process. I can get on temporarily if I use just 'loadbsd
netbsd' and manually mount the system. I will eventually crash again however
with a bus-error!

What causes bus-errors, what should I look for? Does it make any sense to
completely reinstall NetBSD or is it pretty certain that the cause is due to
some hardware problem? Bad RAM? Bad cabling? I have no problems on the Amiga
side; I've noticed nothing flaky about the SCSI transfers at all.

Please Help, I'm going crazy!
