Lo! The wifi connection of my Dell XPS13 (9360) with its QCA6174 sometimes suddenly stops working since I switched to 4.14-rc2+. Every time it happens, there is this error message in dmesg:
> ath10k_pci 0000:3a:00.0: failed to extract amsdu: -11 I have to switch wifi off and on with the hotkey to reconnect. I can trigger the aborts by starting a big download and waiting a few minutes. Sometimes the connections aborts during normal load. Installing the latest firmware didn't help. The wifi works just fine with 4.13.3. While investigating this I noticed a few messages in dmesg that only appear in 4.14-rc (I used 35dbba31be52): > ath10k_pci 0000:3a:00.0: Direct firmware load for > ath10k/pre-cal-pci-0000:3a:00.0.bin failed with error -2 > ath10k_pci 0000:3a:00.0: Direct firmware load for > ath10k/cal-pci-0000:3a:00.0.bin failed with error -2 Do they have anything to do with this?

Side note FYI: I also updated the BIOS of the XPS13 recently (but there is a newer one available that I haven't installed yet) and switched to a newer Fedora version, but that afaics hasn't anything to do with this, as 4.13 works just fine (famous last words...)
