This bug report is about systems that are *not* making use of
SCHED_IDLE, which are probably not due to the known scheduler bug. This
particular error message typically indicates a lock ordering bug or
infinite delay while holding a lock, and can be caused by any kernel
component.
One such case was fixed in version 2.6.26-16:
* Fix soft lockups caused by one md resync blocking on another due
to sharing the same device (closes: #514627)
