SubjectRe: AIC7xxx errors in 2.2.19 but not in 2.2.18
Hi,
2.2.19 only has the 'old' driver. The 'raid/scsi new' problem is a notifier
chain sequence problem that seems to have been taken care of now.
What I do see here may be a coincidence of kernel upgrade and a faulty drive.
Some snippets of 2.2.19 log messages of a faulty drive below.

May 2 03:33:07 pollux kernel: (scsi1:0:1:0) Parity error during Data-In phase.

May 2 03:33:39 pollux kernel: SCSI host 1 abort (pid 1188263) timed out -
resetting
May 2 03:33:39 pollux kernel: SCSI bus is being reset for host 1 channel 0
May 2 03:33:41 pollux kernel: SCSI host 1 reset (pid 1188263) timed out again -
May 2 03:33:41 pollux kernel: probably an unrecoverable SCSI bus or device
hang.
