Description: iwlwifi - Intel Wireless 8265 / 8275 broken

Am on a system76 Gazelle. If I downgrade to 4.14.x things seem to work fine. 4.19 is where things broke for me using 'linux' as well.

Additional info:
* package version: 4.19.13-1
* using netctl for wireless config

Steps to reproduce: Boot system, try to load iwlwifi, find that it cannot be loaded

I encountered this issue a few months back with the 'linux' package, but that quickly broke so I switched to linux-lts where iwlwifi loaded and worked fine. Now it seems that linux-lts has caught up enough and the bug has been introduced here as well. Any 4.19 kernel will not load iwlwifi for me. I am willing to provide any additional log output or try any additional steps to get this working.
This task depends upon

That's why you should have reported such upstream bug to the kernel developers when initially hitting the issue. So please report it now there and report back here if there some solution.
