Description:

When suspending to ram and resuming (via wake on lan) video output appears completely currupted, this
affects both X and the virtual consoles. My keyboard doesn't accept input either, but I can ssh in.

A related bug might be that with KMS enabled mode

From Xorg.0.log.old:

Steps to reproduce:
enable "early start" kms via grub
use mkinitcpio to generate an initial ramdisk
reboot then suspend to ram
issue wake on lan magic packet

*Note: I haven't confirmed if this affects non wake-on-lan resume from suspend, or "late start" kms. I realize this is almost certainly an upstream bug and will report it to freedesktop.org as well.
