reg dump
Ryan has a swanky new Haswell workstation and when he runs xset dpms force off
(or unblanks the lock screen in gnome) he sees screen corruption. The output
looks like a sometimes mangled view into previous screen contents. When a
fullscreen redraw is forced then it corrects itself. (will attach picture).
we've tried disabling fbc and powersave on the kernel command line and that
doesn't help.
will attach dmesg, vbios, and reg dump. The latter was done once before
reproducing, once immediately after forcing screen blanked, once a second
later, and once after we'd refreshed the screen.</pre>
