--- Comment #4 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
The glk fail could be some kind of DSI specific issue:
<3> [96.643905] [drm:dpi_send_cmd.constprop.5 [i915]] *ERROR* Video mode
command 0x00000042 send failed.

The ICL fail could be related to the mismanagement of type C ports:
<7>[  120.123471] [drm:intel_power_well_enable [i915]] enabling DDI C IO
<4>[  120.125029] ------------[ cut here ]------------
<4>[  120.125031] WARN_ON(intel_wait_for_register(dev_priv, regs->driver, (0x1
<< ((pw_idx) * 2)), (0x1 << ((pw_idx) * 2)), 1))

The chv and bdw fails are a mystery.

I suggest splitting this up to different bugs for each platform.
