Subject2.6.26-rc2-mm1 + 2 hotfixes -- possible recursive locking: swapper/1 is trying to acquire lock: (&cls->mutex){--..}, at: [<c02a6564>] device_add+0x3ef/0x4ec
=============================================
[ INFO: possible recursive locking detected ]
2.6.26-rc2-mm1 #8
---------------------------------------------
swapper/1 is trying to acquire lock:
(&cls->mutex){--..}, at: [<c02a6564>] device_add+0x3ef/0x4ec

but task is already holding lock:
(&cls->mutex){--..}, at: [<c02a82e7>] class_for_each_device+0x29/0x95

other info that might help us debug this:
1 lock held by swapper/1:
#0: (&cls->mutex){--..}, at: [<c02a82e7>] class_for_each_device+0x29/0x95
