Hello, Recently my "Killer Wireless-AC 1535" card has been playing up after resuming from S3. It wasn't 100% stable before but usually I was able to fix it by either rmmod'ing the driver (ath10k_pci) or restarting sys-net.

However, this is after! adding ath10k_pci to /rw/config/suspend-module-blacklist (and I do not see the module being removed/readded in dmesg). Will do more investigation but a quick search on github and qubes-users didn't yield any relevant results.
