Newly updated linux-firmware (18.20)

Booted fine, went to launch a fullscreen Wine game, threw the error.

Reverted linux-firmware

log3.txt

This time even after revert SDDM/Plasma failed to load and subsequent driver
driver.

I realized that the working state I was in was due to amdgpu.dc=0 and not the
version of the firmware. 

Both of those logs are with amdgpu.dc=1 and exhibit the crash no matter the
firmware version.

I am currently booted into 18.20 firmware and amdgpu.dc=0 and everything is
working.
