ath10k firmware crashes killing wifi connectivity

Every so often (once or twice a day), I lose connection to wifi. dmesg shows the following:

This has been happening for ~2 months, and is only resolved by restarting NetworkManager. It's a Dell XPS 15 9550 (skylake model.

Any suggestions as to where I can start looking to resolve this?

First make sure your packages are up to date (esp. linux-firmware, which looks like it is) and you've rebooted. If you still have the issue, email the ath10k mailing list: https://wireless.wiki.kernel.org/en/use … 0k/support . You might want to also reference this mail posted to the linux-wireless ml: https://www.spinics.net/lists/linux-wir … 67495.html which looks to be the same symptom (not just the firmware crashing, but the other logs printed) but didn't get any responses.
