=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.31-rc7Y-00012-g3edf2fb #1
-------------------------------------------------------
pvrusb2-context/969 is trying to acquire lock:
 (cpu_add_remove_lock){+.+.+.}, at: [<c1033f3f>] cpu_maps_update_begin
+0xf/0x20

but task is already holding lock:
 (&hdw->big_lock_mutex){+.+.+.}, at: [<f92ed0e2>] pvr2_hdw_initialize
+0x22/0xde0 [pvrusb2]

which lock already depends on the new lock.


I've attached the complete printed kernel dmesg info.
