There was some discussion about SCSI timeouts and looping but I don't see
any SCSI resets in your log.
I took a look in drivers/scsi/sd.c (I'm running 2.1.130) and I see:
if (SCpnt->sense_buffer[2] == MEDIUM_ERROR) {
printk("scsi%d: MEDIUM ERROR on channel %d, id %d, lun %d, CDB:
",
SCpnt->host->host_no, (int) SCpnt->channel,
(int) SCpnt->target, (int) SCpnt->lun);
print_command(SCpnt->cmnd);
print_sense("sd", SCpnt);
SCpnt = end_scsi_request(SCpnt, 0, block_sectors);
requeue_sd_request(SCpnt);
return;
}
If you can repeat this error at will (and it sounds like you can) how about
commenting out the "requeue_sd_request". It looks like that should allow it
to continue...but you may get a large stream of errors after that...
It would seem to me that requeing is a hopeless cause in this situation...
