Subject: 3.5.0-rc3 - i915 gmbus dpb timed out

Hello,

I've booted a few seconds ago to a freshly compiled 3.5.0-rc3 kernel, and
short after starting X + KDE, I've got :

Jun 25 19:16:58 tux kernel: [drm] GMBUS [i915 gmbus dpb] timed out, falling
back to bit banging on pin 5

in my messages.
Nothing like that before (3.4.0-vanilla), and 3.5.0-rc4 not yet compiled.

Anything I should check and/or report to help ?

Best
Paul

Nope, everything works as expected. This is purely an informational
message (and we might need to create a patch to make it go away on
non-debug settings).
