Bug#908632: linux-image-4.19.0-rc3-amd64-unsigned: kernel 4.19 fails to load amdgpu driver on R9 270X.

[aguilar.sanchez.antonio@gmail.com]

Hi!

This also happens to me with an amd 290 card, radeonsi and kernel
options to force amdgpu driver on /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet radeon.si_support=0
radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1"

I'm running Debian unstable and it was working fine until I upgraded
today to kernel 4.19.9-1. 

dmesg shows:

    6.084494] [drm] vm size is 128 GB, 2 levels, block size is 10-bit,

I have the correct firmwares installed:
