Summary: [HSW] linux next-20170407+ boots to a blank screen
Product: DRI

next-20170324 with fastboot=1, shows suspend/resume, works fine
Ever since next-20170407 (last good next-20170324, versions in-between not
tested) my laptops screen stopped turning on after resuming.
Upon removing i915.fastboot=1 from cmdline, the display now turns off
immediately after boot, which means enabling fastboot only covered up the real
issue.
HW:
i7-4500U Haswell with HD 4400
