Description Rik Theys 2022-05-30 09:21:13 UTC

Description of problem:

When the RHEL 8.6 kernel boots on a system with an Intel wireless network card (iwlwifi driver) and the iwlwifi module can not load the firmware, the system kernel panics.

This was not an issue with the RHEL 8.5 kernel.


Version-Release number of selected component (if applicable):

Hardware: 05:00.0 Network controller: Intel Corporation Wireless 3165 (rev 79)

kernel-4.18.0-372.9.1.el8.x86_64

How reproducible:


Steps to Reproduce:
1. Remove all iwl*-firmware packages
2. Boot the RHEL 8.5 kernel -> works
3. Boot the RHEL 8.6 kernel -> panics

Actual results:
Kernel panic on boot


Expected results:
Kernel continues to boot without a functioning iwlwifi wireless connection.
