oops kernel message

Booting latest amd-staging-drm-next is causing kernel OOPS.

Hardware is Lenovo netbook G50-45 A6 6310 APU with R4 Mullins. Kernel booted
with "amdgpu.dc=1" and "amdgpu.dpm=1". 

Blank eDP screen can be caused by another bug:
https://bugs.freedesktop.org/show_bug.cgi?id=106940, but three is no picture on
connected HDMI monitor also (opposite to the situation in mentioned bug
report).

Panic message, that I've got from pstore, attached.
