--- Comment #9 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
[    4.550517] [drm:intel_dp_hpd_pulse [i915]] ESI: 41 00 00 00 00 00 00 00 00
00 00 00 81 01

According to that the sink thinks everything is fine, so no idea why generates
short hpds.

Could be some kind of PSR fail. Please try passing i915.enable_psr=0 to the
kernel cmdline.
