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

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3167 has been updated by daftaupe.


I tried booting the latest release medium available (6.2.2) and master, but can't get past that EFI framebuffer information on my Dell Chromebook 7310.
I've seen on the screenshot you tried loading drm and i915, I tried the same but that didn't change anything unfortunately.

I have no idea if the system is booting behind the scene or if it's stuck.

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.
