4 years ago This may be a mac80211 air-time-fairness issue, not sure it is related to ath10k at all. Is system unstable in any way you can notice? Plz post this to openwrt mailing list, though we can keep the bug open here as well.

Good deal. Sent to the devel list.
Normal temperatures, known good hardware
Behavior: After the crash, wireless was spotty/dropping packets, from what I could tell - came back to normal after reboot.
Outside of that oops, it has been a great device - so thanks for keeping this fork updated. :)

4 years ago I'll be sending this to the devel list - my original post is currently stuck in moderation due to the title? Weird.
It did crash again today though:

If this is airtime fairness again, I can delete these messages. Just trying to help out where I can.

I can try to actively debug/bisect if interested, as I sure am.
