Comment 37 for bug 1730331

Same, XPS 15 9575 running Fedora 29
linux-firmware-20181219-89.git0f22c852.fc28.src.rpm

For me it goes out a few times a day, started fairly recently. `rmmod ath10k_pci` seems to lock everything up completely (tried to reload it at first). Restarting each time "works" but requires a hard reset (shutdown hangs on firewalld).

Haven't tried the rescan trick yet.
