3.13.0-rc4+: Warning at drivers/gpu/drm/i915/intel_display.c
From: Carlos R. Mafra
Date: Tue Dec 17 2013 - 20:38:44 EST
I've been using an external monitor with my retina Macbook and sometimes I see
the warning below. I think it happens when I unplug the monitor from the
thunderbolt port (I use a converter to VGA).

My config contains these options
CONFIG_DRM=y
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_KMS_FB_HELPER=y
CONFIG_DRM_I915=y
CONFIG_DRM_I915_KMS=y
CONFIG_DRM_I915_FBDEV=y
and I should be able to upload the full config somewhere if necessary.
I'm happy to provide any other information.
