When resuming from suspend on 4.15-rc2 the DC stack *usually* =
wakes up displays
after some waiting on this Polaris card compared to non-DC code which flips
them on instantly.

I've encountered the following issues with my dual head setup (native DVI a=
nd
HDMI->DVI adapter):

 - it takes long (2-5 seconds) for the outputs to come up
 - Xfce thinks both of the display were hotplugged causing all kinds of
desktop/windowing related issues
 - sometimes corrupted image on both outputs and the outputs are reset after
waiting for 20 seconds or so, sometimes they come up, sometimes the corrupt=
ion
stays, the system is unresponsive to input while that's going on

I have zero issues without DC. Waking up works 100% of the time and Xfce ne=
ver
thinks the displays were hotplugged.

Currently I have no logs from kernel from that time. Hope this description =
is
enough.
