So the initial report was premature. I've since tried with more
firmwares only to find that they all crash. Even -ct.

The basic problem is that in the case of the firmware crashing, -ct
restarts the firmware whereas ath10k dies with it.

I've concluded that it's my phone running Android Oreo that causes all
the firmware crashing.
