--- Comment #6 from Eddie Ringle <eddie at ringle.io> ---
Wanted to add that I'm seeing this issue now under a similar setup. I've seen
it in the past, but the last few kernel releases have been pretty smooth. Once
I upgraded to GNOME 3.26, however, both 4.13 and now 4.14-rc3 are displaying
this issue.

I'm on Arch (using Wayland primarily), with a Fury X and three Dell P2415Q
monitors, also connected via DisplayPort. I have MST disabled on all three,
since (even Dell has documented) this model has issues hitting 4K at 60Hz with it
enabled.

Same "displayport link status failed" and "clock recovery failed" messages
appear for me, also three times in a row. This more often than not leads to
gnome-shell crashing. I see it most often after I've put my computer to sleep
when I try to wake it up. Other times when putting it to sleep, one monitor
will stay powered and show a backlit blank screen.
