(Get the code!)
Initially this looked similar to bug 1413540.
This bug patched 3.13 with 9242b5b to _mitigate_ the issue, but this patch is already present in 3.16. So perhaps we're hitting another failure mode.
It would be good to know if the smp_call_function_* path in the backtrace is actually leading up to an IPI call that gets lost, and thus we spin in csd_lock_wait.
Are you running nested KVM instances? How often does this lockup occur? Can you get crashdumps of this issue?
Thanks,
