Comment 77 for bug 1238902

I started bisecting kernel from 3.7 to 3.8 this is the bisect log output:

git bisect bad 992956189de58cae9f2be40585bc25105cd7c5ad

I stopped as the second kernel test, the 992956189de58cae9f2be40585bc25105cd7c5ad one, after suspension gave me a black screen and I could not resume, had to switch of my PC by pushing power button.
After reboot apport reported an Xorg crash.
So I think the problem is on this kernel commit (992956189de58cae9f2be40585bc25105cd7c5ad).
