That's interesting. Did the card ever work as AP with ath10k for you?
By "any platform" you mean you tested on both little- and big- endian
machines?

My current guess is this could have something to do with AP beaconing
- if it was to get an invalid dma pointer it could crash the device so
hard as to effectively prevent host from accessing register dump
memory.
