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.

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