As described in the linked message:

I've just started to play with a new Acer Aspire S5 test box and noticed that
garbage is displayed after resume from suspend to RAM with the 3.10 kernel
(under KDE 4.10.3 on openSUSE 12.3).  The display corruption goes away after
killing X and restarting it.

The CPU is a Core i5-3317U (Ivy Bridge), i915 graphics.

That doesn't happen with 3.9 (same config otherwise).

Also it turns out to happen on an SNB-based machine (not 100% of the time).
