Created attachment 100071 [details] lspci -vv (from the older kernel) I have Acer 4820TG 14" laptop and 22" external monitor (connected by VGA). Console is rendered with resolution of the smaller monitor, and on the second one it is displayed in the top-left corner with unused bottom and right space on the monitor (is it a bug, too?). These borders are used to be black (on 3.8.8, for example), but on recent git snapshot it is filled with random colored garbage after resuming from hibernation. I can try to bisect this issue later.
Looks like we need commit d8241785c24d4508ecc26fb91b28b39a0dd26070 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Apr 27 12:44:16 2013 +0100 drm/i915: Only print the info message about incresing stolen size for FBC once for the resume path, too.
