dmesg output 4.18rc5 + drm-fixes-2018-07-20

OK, so I have some new, probably interesting dmesg output with the latest
mainline build.

What's happening here is that the system boots up, then my background displ=
ay
brightness service goes to work (see here: https://github.com/FedeDP/Clight and
here: https://github.com/Fede=
DP/Clightd) and tries to adjust screen brightness.
This leads to a number of=20

  RIP: 0010:dm_dp_aux_transfer+0xa5/0xb0 [amdgpu]

trace calls and then the system freeezes completely. And I mean completely,=
 as
in not even sysrq + REISUB does anything. Does this help in any way?
