dmesg on HSW Desktop

Environment:
--------------------------
Kernel: (master)6e4664525b1db28f8c4e1130957f70a94c19213e

    Linux 3.11

Bug Details:
---------------------------
I-G-T testdisplay causes call trace while setting up customized timing. This issue happens on 3.11 release kernel, the same bug has been fixed on latest kernel(bug#65442).
I grabbed the dmesg info on a HSW Desktop and attached it. You can see the whole system booting dmesg and the call trace after doing "testdisplay -f".

Reproduce Step:
-----------------------------
./testdisplay -f 38.25,800,832,912,1024,600,603,607,624
