thinkpad x230t: Xorg eating my CPU after wake from zzz

[Edd Barrett]

Hi,

An issue that I have known about for a while, but keep forgetting to
report.

If I zzz my thinkpad x230t, when it wakes the fans start spinning up.
Upon inspection of top(1), I see that X is eating a core:

  PID USERNAME PRI NICE  SIZE   RES STATE     WAIT      TIME    CPU COMMAND    
24512 _x11      64    0   16M   21M onproc/0  gemwt     3:11 91.70% Xorg        

Prior to zzz, X is use about 3% of a core.

I notice that switching to a virtual terminal and back to X fixes this until
the next zzz. I have gotten into the habit of doing this after every zzz to
save my battery.

I noticed this months ago, so the problem is not new.

Dmesg follows (I zzz and woke the machine several times):
