Comment 5 for bug 1373969

I've got a bit more info.

As you can also see in the 'mainline kernel install log' attachment, since this same update, I also have a graphics driver problem: no more opengl/hardware accelleration, with all of the 3 driver options (fglrx, fglrx-updates, xorg). Before I used fglrx-updates because this seemed to work the best of the 3 (not good, but better than the rest).

After install of the mainline kernel, I tried switching to the xorg option: still no opengl, but at least suspend/resume seems to work now! When I resume the computer, I get a flash of random multicolored dots and stripes, but I don't have to ctrl-alt-del anymore.
