Subject: SCSI Oops (was test12-pre4)

(cross-posted to linux-kernel and linux-scsi)

Hi,

The SCSI oops I reported last week is still present in test12-pre4.
This is on a Dell PowerEdge 6300. It has two Adaptec AIC-7890, one
Adaptec AIC-7860, and an AMI MegaRAID controller. There's nothing on
the 7890s, a CDROM and a tape drive on the 7890.

With all of the above enabled the kernel boots with no problems.
However, if I disable the two 7890s from the BIOS (to save 30 seconds
of boot time), I get an oops.

The decoded oops is below. Please email me directly for further
information.

Thanks,
Borislav

Could you find out exactly when this broke?
