With 4.7.0 it booted but no X display could start
With 4.8-rcX it deadlocks on bootup now.

displayed and deadlocks bootup.
2) It the lid is closed, a panic message is shown (and deadlocks bootup).

Trying to enable PRIME on AMDGPU with CIK experimental enabled fails. attac=
hed
to this BZ is dmesg of oops from 4.7.0 kernel, the stack is the same for
4.8-rcX.

PRIME has never worked for me on AMDGPU it has worked on regular radeon
however.
