This kernel is larded up with a fair amount of my patches, so it
could be my bug. But, in case someone sees something similar,
here's my crash:
It hit this BUG_ON in core.h:
static inline
struct cfg80211_registered_device *wiphy_to_dev(struct wiphy *wiphy)
{
BUG_ON(!wiphy);
return container_of(wiphy, struct cfg80211_registered_device, wiphy);
}
Test system was 32 ath10k stations, and I had just rebooted the AP
machine...

Ahhh, a bit further up in the logs I notice my ath10k has decided
firmware is hung and so it's resetting itself...that is likely
the case of this..will go poke around there...
