Shimon,
We've been noticing some disturbing behavior with both v1.1.10 and v1.2.0 of
the dpt driver. In a nutshell, we cant have unattended reboots. I think the
best way of describing the problem, is with dmesg outputs.
[shutdown box]
syncing disks... 2 done
dpt0: Shutting down (mode 0) HBA. Please wait...dpt0: Controller was warned of shutdown and is now disabled
Rebooting...

dpt0 ERROR: Command "Test Unit Ready [7.24]" recieved for b0t1u0
but controller is shutdown. Aborting...
[repeated *many* times, followed by eventually]
panic: cannot mount root
This is, of course, a problem :) The only way I've been able to ameliorate the
situation is to boot the machine with an older version of the dpt driver (from
floppy no less), wait for it to come up. and reboot with the new driver.
Any suggestions?
