Release: up-to-date Focal LTS (20.04.3)
Package-version: linux-firmware 1.187.20
Hardware model: [AMD/ATI] Chelsea LP [Radeon HD 7730M]
With the latest kernel upgrade (5.4 --> 5.11, if I recall correctly), my
laptop's discrete graphics stopped working. Looking at the logs, I found
these messages:
-- snippet --

In fact, file '/lib/firmware/amdgpu/verde_uvd.bin' was missing. Running
'$ dpkg -L linux-firmware | sort' gives this:

Copying the file from upstream
(https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/tree/amdgpu/verde_uvd.bin) didn't work on my system,
probably because I use UEFI and the module wasn't signed (error below):
-- snippet --

I can confirm that reverting kernel driver to 'radeonsi' makes the
device usable again, but at the expense of Vulkan APIs (not supported by
this driver).
Could you, please, fix this?
