I've been observing this bug in other kernel versions and other hardware configurations, so I think it's easily reproductible.

Happens when I/O error on external ide <-> usb drives. Can be reproduced by unplugging the usb cable while accessing the drive, or with a faulty drive.

I don't think my real u2w scsi controllers would like the real scsi disks being hot swapped, so I haven't tried there.

Regards.

I've been observing this bug in other kernel versions and other hardware configurations, so I think it's easily reproductible.
Happens when I/O error on external ide <-> usb drives. Can be reproduced by unplugging the usb cable while accessing the drive, or with a faulty drive.
I don't think my real u2w scsi controllers would like the real scsi disks being hot swapped, so I haven't tried there.
Regards.

Thanks. It looks like it may possibly not be an elevator specific oops. Can you try booting with elevator=deadline and see if you can reproduce the oops please?

It's not, it clearly looks like SCSI trying to kill off the queue with pending commands.

That's what it looks like to me too ... there should be a fix for this in the scsi-misc-2.6 tree.

It happens more of the same. This time I reproduced by just unplugging the cable while writting.

Another side problem I have observed about this:

Processes that call sync() get stuck into D state, for example shutdown.

It's not, it clearly looks like SCSI trying to kill off the queue with pending commands.
That's what it looks like to me too ... there should be a fix for this in the scsi-misc-2.6 tree.

There also was a fix for usb-storage just submitted for the gregkh-2.6 tree:

http://marc.theaimsgroup.com/?l=linux-usb-devel&m=109744234829347&w=2

It should help prevent the condition that triggers this situation.
