Dmesg file

I followed the instructions here (https://01.org/linuxgraphics/documentation/how-debug-suspend-resume-issues-0) and they told me to post stuff here asking for help. I included the DMESG record that they had me create within those instructions.

The symptoms are that my computer's screen is completely black and non responsive, even when the rest of the system has completely woken up.

So the rest of the system is still responsive though? There are no obvious radeon driver related problems in dmesg, so it sounds like it just fails to light up the screen after resume.

Did this already happen with older kernels, or is it a regression?

About 2 years ago I think I got it to work with arch, but otherwise it's pretty much never worked.

Is there a way to get it to get the screen on and showing the pretty things?
