[Intel-gfx] bad panel power sequencing delays, disabling panel

Sat Oct 13 07:28:34 CEST 2012

On my Macbook Retina 2012, after a recent firmware update, i915 fails
to use the eDP-1 panel [1], which goes blank when switched to. Nouveau
works correctly though [2]. I see this behaviour on 3.6-rc to 3.6.2.

Full boot and IGD switch (see end) kernel logs at
http://quora.org/2012/mbp-i915-panel.txt with drm.debug=0x6. What
additional information is needed to diagnose this?

Thanks,
  Daniel
