The interesting ones will be the ones before & after you hit that
BUG: warning at /usr/src/linux-work1/kernel/cpu.c:51/unlock_cpu_hotplug()
if you can make that happen again.

I don't see nothing interesting before BUG: warning at
/usr/src/linux-git/kernel/cpu.c:51/unlock_cpu_hotplug()

Only

CPU0 called lock_cpu_hotplug() for app amarokapp. recursive_depth=0
[<c01329ab>] lock_cpu_hotplug+0x36/0xb9
[<c01182ce>] sched_getaffinity+0xf/0x83
[<c0118361>] sys_sched_getaffinity+0x1f/0x41
[<c0102d51>] sysenter_past_esp+0x56/0x79
amarokapp acquired cpu_bitmask_lock

appears after this warning.
