Kernel log when failing to boot normally
I've been having problems booting when using a self-compiled kernel of the
drm-next-4.3 branch from the agd5f repo. The amdgpu kernel driver complains
that some va (virtual address?) conflicts with another, which makes it boot to
a terminal.
You can see the conflict in the kernel log:

ffff880620b34800 va 0x0000100000-0x0000100400 conflict with

0x0000100000-0x0000100400
I do not have these problems when using a self-compiled kernel from the
drm-next-4.2 or drm-fixes-4.2 branch, so something must have changed from 4.2
to 4.3 that causes the conflict.
Using a Radeon R9 285 (TONGA) on Kubuntu vivid with mesa 11 from the oibaf ppa
and a self-compiled xf86-video-amdgpu.</pre>
