Interesting, that indeed that should work. Could be a bug in the VESA BIOS =
or
the driver touching the hardware even if it decided not to do so.
Please try booting with modprobe.blacklist=3Damdgpu on the kernel commandli=
ne.

Not the slightest idea when Vega10 support was added to Mesa, but 17.2.4 is
only a few days old so that could work.
I would try to get X working with only the kernel first. If you have that
working and still no OpenGL you can still compile Mesa on your own.
Alex Kernel branch is here BTW: https://cgit.freedesktop.org/~agd5f/linux/
You can also find a amd-staging-4.13 branch there, but that is a ~month old=
and
not maintained any more. amd-staging-drm-next is the latest development wor=
k.
