Panic at sos load on RX 6500XT (amdgpu beige goby)

[colfrog]

Describe the bug
The module fails when loading the firmware, specifically the sos. I've tried using the drm-kmod meta-package without doing anything else, loading the modules manually, and cloning linux-firmware in /boot/firmware. See the attached crash reports. I assumed at first that the issue was with loading the firmware, but it seems the issue is elsewhere, because it finds the VCN even when it fails to load the firmware files.

DRM KMOD version
drm-61-kmod 6.1.92.1402000_3

To Reproduce
Load amdgpu on a beige goby graphics card (RX 6500XT) with only drm-61-kmod and gpu-firmware-amd-kmod-beige-goby installed. The drm-kmod meta-package gives the same results. drm-515-kmod gives the same results, the card is unsupported on drm-510-kmod.
