            Bug ID: 220230
           Summary: linux-firmware 20250613 breaks AMD iGPU
           Product: Drivers
           Version: 2.5
          Hardware: Intel
                OS: Linux
            Status: NEW
          Severity: high
          Priority: P3
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: therealgraysky@proton.me
        Regression: No

Upon booting the system with the tagged version of linux-firmware 20250613
installed, iGPU on the Ryzen 9950X does not work. The monitor does not detect a
signal and the following is printed to journalctl. Could this be related to the
following commit?
