 ironlake_panel_vdd_off_sync+0xef/0x100 [i915]()

Hi Daniel,

On 3.9-rc1, I get the following warning on my MacBook Pro Retina.

Graphics still seem to work ok, but I think that's because it's really
using the nouveau driver instead of the intel driver (so David says).

Anything I can do to test to try to fix this?

thanks,

greg k-h
