Subject: [Regression in 3.10] Garbage displayed after resume on Acer Aspire S5

Hi,

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).  It also doesn't happen
with my older Sandy Bridge-based box (with 3.10), so I suspect Ivy Bridge
specifics.

Is this known?  Do you want me to bisect?

Rafael
