Created attachment 67249 [details] [review] testing patch
If my 3.7 branch by itself doesn't work, does this patch on top of my 3.7 branch help? Please attach the output of dmesg after resume with this patch applied.
attached (the added DRM_INFO yields "bl_level: 0xff" )
as an additional experiment, I used "kexec" after suspending to reboot the same kernel and let the radeon driver do a full reinitialization -- but even that fails to bring the display back to life :(
Anything further I can do?
