This crash is occurring whenever I disconnect from a wireless network. The uuid printed for the crash is aa5d3a3c-6b76-4da3-b8f3-c7500b7e4070. I was able to reproduce this in stable kernel 4.11.3 and also in a recent git version. More info about the crash can be found at the bottom of the attached dmesg log. Please let me know if more info is needed.

Same problem on 4.11.6, Dell XPS13 9343. I had this problem back in October on 4.8.4. It wasn't the only problem, the device was practically unusable and as it was killing my productivity I put back my Intel 7265 card.
Just put back the card with the idea of reporting all the problems with it, in the hopes of getting it fixed, as I suspect the Intel is causing my occasional hard lock-up during resume.

I encounter the same bug. It does not seems to be critical as driver is able to recover and function normally after F/W crash. Anyway I traced it using:
trace-cmd record -e mac80211 -e ath10k -e cfg80211
to get more information about the problem. Logs are available here:
I can perform more debug/testing if needed.
