dmesg

I'm using the radeon module with KMS enabled. On resume from suspend, my laptop
screen stays turned off. I know that the system has resumed properly because an
external display (through hdmi) shows that everything is working.
dmesg attached.

uname -a

I have some btrfs stuff merged into this kernel, but other than that, this is
completely vanilla.
