hmm.. Overlapping emails.
The crash with e2fsck was easily repeatable with the above patch. Just dirty a few buffers and run /sbin/sync. It's due to the __make_request queue_head thing which you fixed in test12-pre3. Yes, this was IDE.
However the original problem of a list_del being performed on a wild pointer is being seen on SCSI systems. I expect the above patch will catch it if it's still happening. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
