Will contact him ASAP, thanks. I did some tests and changed controllers, 
cables, rechecked all SCSI devices and still no go. All indications seem 
to show a driver timing relevant problem and definitely not an interconnect 
issue.

If you ever upgraded a 2.XX firmware to a 3.XX it tells you right there 
that it corrects some type of bug and even asks for a machine reset on the
next boot. Can't recall the exact message though but it seems irrelevant 
to this problem anyway.
