So there must have been two separate problems originally, one of which was solved by the 4.4 merges. I tried hacking the i915 driver code in a few different ways but none of them solved the problem: - always setting force_bit=1 on the 'struct intel_gmbus' - changing the drm_i915_private hotplug_work to a delayed_work and scheduling it with delay 400 ms - increasing the number of retries in drm_do_get_edid() from 4 to 32 - increasing the number of retries of the "live status" check in intel_hdmi_detect() from 3 to 30 Also, I verified that the same monitor and VGA->HDMI adapter works on a Raspberry Pi. So that leaves the Skylake hardware and/or the i915 driver as the source of the problem.
