Mines are v1.1. I didn't have to power cycle them, they still work, somehow recovered themselves, strange.
I found something about configuration files in https://github.com/greearb/ath10k-ct/issues/93
and especially here http://www.candelatech.com/ath10k-10.4.php#config
However, I may turn off irqbalance, at least in my case I didn't have any "internal" crashes in 7d, nor any swba errors. I'll give it try in the next few days and report if got better.
