I've put another syslog file on the web. IMHO it shows all the errors
with the scsi system. It's on
http://laokoon.in-berlin.de/~beutin/syslog.gz
If i can increase the debug level i will do it if it helps!

I cannot imagine a cabling problem, because the drives are in a hot
swap backplane and i changed the places of the drives (but having
the IBM drive every time as the first drive).
Or is it possible to have a bad cable from the board to the backplane,
beeing ok for the U160 IBM drive but not for a U360 drive? I'm using
the SCSI cable coming with the board, but i will try another next
time i've access to the machine.
Do You think, it could help to set the controller maximum to U160 on
the expected SCSI-IDs for the fujitsu drives?

Do You have any idea where to find the firmware an an update tool
for fujitsu drives?

Any hints or help welcome!

Thanks for reading!
