I don't have much experience either and from the reported information I can't tell much. The question would be what the thread which is holding the lock was doing and whether it traces down to IO layer. So, as Jeff said, we'll need sysrq-t output to tell what's going on. The current trace only reveals the victim not the offender. Thanks. -- tejun
