part of DMESG that looks relevant

while booting my PC, amdgpu complains it cannot execute UVD and VCE ring tests
on Fiji GPU (R9 Nano).
The error code -110 points to a timeout.
Maybe R9 Nano needs more time to initialize the UVD decoder in UEFI mode?

Please note that this is not critical to me at all: I only use this card to
perform OpenCL calculations via RoCm, so couldn't care less, but I still think
it's worth to have a look at.
