When booting 2.1.51, the kernel hangs during SCSI device detection:
[...]
scsi target 3 [...] refusing wide [...]
(scsi0:3:0) Reset device active_scb 0
scsi0: (targ 3, chan A) matching scb to (targ 3/chan A)
scsi0: (targ 3, chan A) matching scb to (targ 3/chan A)
scsi0: Unexpected busfree, LASTPHASE=0xe0, SEQADDR=0x4f
Then it spews out kernel debug messages and reboots.
Hardware: Gigabyte GA-586DX w/ onboard AIC7880.

Turning on/off tagged queueing, paging and scsi bios does not help.
Disconnecting the Seagate fixes the problem.
2.0.30 runs just fine.
Is there anything I can do to get the driver running?
