[DragonFlyBSD - Bug #3167] UEFI boot hangs right after initializing UEFI framebuffer

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3167 has been updated by daftaupe.


@mneumann, no that's the initial issue, it doesn't work with the regular console. The GPU is not that recent, it's a Intel HD Graphics 5500 from a Broadwell i3-5005U.
I tried setting drm_load=NO and i915_load=NO but it seems to have no effect as it's probably what's happening as default.

This happens on a recent Tuxedo laptop. See attached screenshot.

I have come up with a working (but hacky) patch:

After patching, if I set loader tunable sc.probe_early=1 then it correctly boots.
