Compiled slub with SMP & CONFIG_PROVE_LOCKING. No luck. It still hangs solid
after the second spinlock lockup call trace.

Here's the relevant sections of the kernel logs:

...

Surprisingly, with CONFIG_SMP=n, CONFIG_PROVE_LOCKING produces this with slub
(then hangs solid):

Freeing unused kernel memory: 188k freed
BUG: spinlock lockup on CPU#0, init/1, ffff81011e9d3160

Call Trace:
 [<ffffffff802eca20>] _raw_spin_lock+0xca/0xe8

 [<ffffffff8020ead0>] sys_mmap+0xe5/0x110
 [<ffffffff80209cce>] system_call+0x7e/0x83

To recap:
1. No problems with slub on CONFIG_SMP=n & CONFIG_PROVE_LOCKING=n
2. Problem with slub on CONFIG_SMP=n & CONFIG_PROVE_LOCKING=y (perhaps a. some
locking issue when slub is activated or b. something is wrong with 'prove
locking' mechanism when slub is activated or c. something else I don't see) 
3. Problem with slub on CONFIG_SMP=y (even without CONFIG_PROVE_LOCKING=y)

Thanks
