Hi Justin,

CC-ing dri-devel as more KMS/radeon people will see it there.

Could you include all the drm/kms/radeon related output from your
kernel log as well as your /proc/cmdline?
Also, are /sys/class/drm/card0* entries present with proper contents
(modes, enabled, status attributes present and with sensible values)?

What exact AMD/ATI GPU is present in your system (lspci)?

Are your graphics drivers built-in or built as a module?

Bruno
