<pre>(Dell 7480, Intel HD 620 rev 02)
PROBLEM I upgraded kernel 4.14 -> 4.16 and am now seeing the desktop
consistently hang after boot, near immediately after gdm launches. As in, I
can't choose a user from the list, because mouse freezes in a few seconds.
I see the bug subject keywords in systemd journal as the only visible error
(i915 debug not enabled):
```
apr 21 10:55:54 papaya kernel: [drm:drm_atomic_helper_wait_for_flip_done
[drm_kms_helper]] *ERROR* [CRTC:37:pipe A] flip_done timed out
```
My `i915` configuration has traditionally been `options i915 enable_rc6=1
enable_fbc=1 enable_psr=1` and it has worked without issues on older kernels.
I learned 4.16 eliminated the `enable_rc6` parameter, so we can rule this one
out.
SOLUTION commenting out `enable_fbc=1 enable_psr=1` seems to have restored
operational capacity and the system has not frozen for several hours.
It does seem like REOPENED is the correct status here?</pre>
