While my box was busy building randconfig kernels I noticed this in dmesg:

================================================== =====
[ INFO: possible circular locking dependency detected ]
2.6.25-03562-g3dc5063 #1
-------------------------------------------------------
X/1332 is trying to acquire lock:
(&rq->rq_lock_key){++..}, at: [] task_rq_lock+0x3c/0x70

but task is already holding lock:
(&cpu_base->lock){++..}, at: [] lock_hrtimer_base+0x23/0x50

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:
