Doing `sudo rm /etc/modprobe.d/blacklist-amdgpu.conf` fixed my issue. I
have no idea why this file was created and why the old kernel worked
when the new one didn't.
Either way, this is not a kernel issue.

Title:
llvmpipe used instead of amdgpu
Status in linux package in Ubuntu:
Invalid
Bug description:
When I boot into Linux 5.8.0-44, I get a 1024x768 resolution instead
of full monitor resolution. About page in settings shows that
`llvmpipe (LLVM 11.0.0, 256 bits)` is used instead of amdgpu.
This is a regression in Linux 5.8.0-44, the previous versions
(5.8.0-43 and 5.8.0-41) work fine. I've also tested the proposed
version (5.8.0-45) and it also had this issue.
