This may be yet another red herring, but you indicate the presence of THRE 
devices with "switchable active termination".  If you and I think of the 
same thing when you say Active Termination, your problem may be due to 
the fact that three devices are each fighting for the opportunity to be the 
terminating device.  You really ought to only have one such device at THE 
END of the scsi chain.  If they really are active and switchable, disable the 
active termination on all but your chosen last device.  If they aren't truly 
active, merely switchable, then only have the last one in the chain 
switched on.  You could also try ALL TERMINATION SWITCHED OFF.  ( I 
have a mac LC2 which won't boot at all if its SCSI chain is terminated - 
work that one out).  If none of this helps - sorry.
