The aic79xx driver shat itself.

The log buffer starts with

scsi1 (4:0): rejecting I/O to offline device
scsi1 (4:0): rejecting I/O to offline device
scsi1 (4:0): rejecting I/O to offline device

started.  A serial console would be nice.

Are all the failures due to the aic79xx driver failing in this manner?  If
not then please report the different failures separately, thanks.
