On two different Sandy Bridge machines, modprobe eeprom does this:
[ 35.627075] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.679006] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.730938] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.782889] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.834804] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.886739] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.938654] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 35.990588] [drm] GMBUS timed out, falling back to bit banging on
pin 0 [i915 gmbus disabled]
[ 36.042539] [drm] GMBUS timed out, falling back to bit banging on
pin 1 [i915 gmbus ssc]
and hangs forever. 100% reproducible, and it might be a 2.6.39 regression.
Maybe this is a hint for some of the display-detection issues.
