Hello everyone and dear developers,
I’ve encountered a strange bug with TurrisOS 5.1.4.
After installing the latest medkit, my 5 GHz wifi doesn’t seem to want to come up.
I know for sure that my card isn’t defective as this morning on TurrisOS 4 it was still working perfectly.
In my system logs I find the following error multiple times regarding the ath10k driver:

I’m quite sure this problem originates from the original OpenWRT source drop as multiple users have reported this issue with the ath10k driver.
It seems that it has something to do with DFS.
I am able to get the 5 GHz wifi up and running by locking the channel to a non-DFS channel for instance 36.
When setting channel selection to auto again, the driver fails again.
Hopefully this bug report can help you guys triage this problem and solve it.
When more help is needed, I’m happy to provide more details/test some stuff.
