I think there are two bugs here:

1) Cold reset doesn't always work, Michal has a patch for that. That's
   why the wakeup fails:

http://lists.infradead.org/pipermail/ath10k/2013-October/000638.html

2) We enable interrupts too early and if wakeup fails and we get a
   spurious interrupt ath10k crashes. We don't have a fix for this yet.
