Summary: SCSI: timing out command for dvd drive
Product: IO/Storage
Version: 2.5
KernelVersion: 2.6.28-rc1
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: SCSI
AssignedTo: linux-scsi@vger.kernel.org
ReportedBy: bugzilla-kernel@jensthebrain.de
Latest working kernel version: 2.6.27
Earliest failing kernel version: 2.6.28-rc1
Distribution: Gentoo
Hardware Environment: Dell Latitude E6500
Problem Description:
I tried 2.6.28-rc1 today and the boot is delayed by scsi timeouts. It does work
if I remove my dvd drive before booting.

James, you are correct, this is the same problem. Applying the patch at
http://lkml.org/lkml/2008/10/24/102
made my system boot again. Thanks!

I think this caused due to my patch that adds the scsi_noretry_cmd check
in scsi_decide_disposition. We saw this problem exposed in RHEL testing.
Basically what used to happen without my patch is that the command
continuously timed out or we got an error, and we would eventually hit
the cmd->retries and cmd->allowed check and the command would be failed
fairly quietly in some code paths like during setup.
Now scsi_noretry_cmd is returning 0 and that causes us to retry the
command until we hit the check:
disposition = scsi_decide_disposition(cmd);
if (disposition != SUCCESS &&
time_before(cmd->jiffies_at_alloc + wait_for, jiffies)) {
sdev_printk(KERN_ERR, cmd->device,
"timing out command, waited %lus\n",
wait_for/HZ);
disposition = SUCCESS;
}
in scsi_softirq_done so we now see this error message get printed out
for the failure.
Is Mike Anderson's patches that removes scsi_noretry_cmd going to be
merged? If so that will fix the problem. If not then I will make a
different patch.
