dmesg drm-intel-nightly drm.debug=0x1e before suspend

When resuming my Dell XPS 15 9550 from a suspend, the monitor won't turn on
again. Tested all quirks available from pm-suspend, it does not work.

It's not related to X11, it happens also if you suspend without starting X.

The machine also has an 960M nVIDIA card, but the module is not loaded, and the
card is turned off with the help of the bbswitch module. Have tested with the
nvidia driver loaded, it makes no difference. No physical output on the laptop
is wired to the nVIDIA card (tested with starting X with only nvidia loaded, it
shows no outputs available).

Tested both vanilla linux-kernel-4.7.0 and latest drm-intel-nightly (currently
at 4ef516d46da2ae7091ef0b0b8d05f600d2e85ab8). Nothing seems to happen in dmesg
with vanilla kernel, but that was tested without drm.debug=0x1e log_buf_len=1M.

It also gets no error state after resuming from suspend:

# cat /sys/class/drm/card0/error
no error state collected
