Description Matt Fagnani 2019-07-28 01:33:14 UTC 
Description of problem:
I've seen these iwlwifi kernel oopses when booting with 5.3.0-rc0 to 5.3.0-rc1 on most boots (at least 10 times) with the
Fedora-KDE-Live-x86_64-Rawhide-20190724.n.0.iso  https://koji.fedoraproject.org/koji/buildinfo?buildID=1319740 and 
Fedora-KDE-Live-x86_64-Rawhide-20190713.n.1.iso https://koji.fedoraproject.org/koji/buildinfo?buildID=1312763

The Wifi/Bluetooth NIC is an Intel Wireless AC 3168. The Wifi device info from the journal was.

The journal had a iwlwifi microcode firmware error right before the oops in each case like the following. The error 
"kernel: iwlwifi 0000:02:00.0: Failed to get geographic profile info -5" might indicate the problem

That error and oops repeated three times in that boot. I guess the firmware is from iwl3160-firmware-1:25.30.13.0-99.fc31.noarch

I haven't been using the AC 3168 NIC. I could test it out if that would be informative.
