Dmesg of kernel bootup - 4.7.0 kernel
When trying to enable Switchable Graphics, I am unable to bootup.
With 4.7.0 it booted but no X display could start
With 4.8-rcX it deadlocks on bootup now.
1) If the LCD (LVDS) display lid is open, no such kernel panic message is
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. attached
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.
