lspci output
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.

dmesg
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: http://people.redhat.com/sgruszka/qca6174_crash/ I can perform more debug/testing if needed. Created attachment 260313 [details]
