After changed to another monitor, I can boot into X Window now, but the first issue (attached in comment 2) still exist.
Comment 5 Ville Syrjala 2016-04-20 17:43:05 UTC 
Is this still an issue?
Comment 6 Dhinakaran Pandiyan 2016-06-22 19:22:32 UTC 
Please reopen if this is still an issue on the latest drm-intel-nightly.
