Broadwell i915 VT behavior on resume from sleep

Broadwell i915 VT behavior on resume from sleep

[Steven Noonan]

Running 3.19.3 on a Broadwell ThinkPad X250.

I'm running into some unfortunate behaviour. When I resume from sleep,
the GPU occasionally hangs:

https://bugs.freedesktop.org/show_bug.cgi?id=89896

And I also have this issue with the virtual terminals after I resume
(reproduced by doing a suspend/resume followed by a reboot):

Not sure what I'd say in a bug report for this issue. VTs behave fine
if I haven't suspend/resumed at all.

dupe of https://bugs.freedesktop.org/show_bug.cgi?id=88807

would need some further bisecting to fix it in v3.19.x too

I'm confused about what 88807 is talking about. It makes it sound like
it was fixed by 3.19-rc6, but I'm on 3.19.3.

Sorry about that. Moved to unlisted, should be viewable now.

do read comment #6 too

anyway, since it's fixed in 4.0 and up the bug is closed
