Description

Marek found this bug while testing:

BUG: spinlock lockup on CPU#0, bat_events/516, c0200280 
Call Trace: 
[<80048f34>] dump_stack+0x8/0x34

[<800455d4>] kernel_thread_helper+0x10/0x18

this seems to be present in r1397. It rarely occurs ~1 second after loading the module.

Seems the spinlock is held elsewhere.
