This is a reccuring problem, although I received better logging this
time around.
I just got this in my kernel log, the scsi bus has hung completely and
I will shortly have to power cycle the box.

Machine contains BT 958 wide, disks are runnning at:
Queue Depth 28, Wide Synchronous at 20.0 MB/sec, offset 15
scsi0 is active-terminated, scsi1 is terminated by Id5.
Is this just due to lack of active termination on scsi1 - or something
more sinister?
