Public bug reported:
As an owner of a Radeon RX5700 GPU, I was really looking forward to the
Eoan release which includes the Linux Kernel 5.3 and Mesa 19.2 - both
with finally Radeon RX5700 (navi10) support. However, upgrading my
system from Kubuntu 18.10 (working) via 19.04 (does not boot) to 19.10
resulted in a boot failure. Last message shown on the screen is:
fb0: switching to amdgpudrmfb from EFI VGA
After some research I found that the package linux-firmware does not
include the necessary files /lib/firmware/amdgpu/navi10_*. After I
manually copied the missing files from the repository
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git, I was able to boot normally.
Please update the package linux-firmware and add the needed firmware.
