f8bf63fdcb1f82459dae7a3f22ee5ce92f3ea727 is the first bad commit commit f8bf63fdcb1f82459dae7a3f22ee5ce92f3ea727 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> AuthorDate: Fri Jun 13 13:37:54 2014 +0300 Commit: Daniel Vetter <daniel.vetter@ffwll.ch> CommitDate: Mon Jul 7 11:27:52 2014 +0200 drm/i915: Kill duplicated cdclk readout code from i2c We have a slightly different way of readoing out the cdclk in gmbus_set_freq(). Kill that and just call .get_display_clock_speed(). Also need to remove the GMBUSFREQ update from intel_i2c_reset() since that gets called way too early. Let's do it in intel_modeset_init_hw() instead, and also pull the initial vlv_cdclk_freq update there from init_clock gating.

But revert the bad commit base on latest commit (f68d697eaf3278200a7fc3c8b1d95d72837b84d8), the test still causes system hang
Please retest on current nightly.

Ville, did we change something here that could've fixed this?
