I'm running FreeBSD 11.0-CURRENT r292595 on ThinkPad T430 (i7-3520M,

Something has been broken somewhere between r296485 and r297692,
I suspect namely i915kms - it won't boot: at the boot screen I see that
all modules are loaded, then after "Booting..." message at the bottom
screen turns black in 1-2 seconds of booting process, it seems to be the
point when it regularly switches to native resolution.
Can somebody shed light on it? What can I check to get more info on
this?
Regularly I update to the revisions used to build snapshots at:
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/11.0/
assuming that those revisions have less issues. So tried a few, including
the head. None worked for me after a certain revision (from the range I
mentioned above).
Thanks for advices!
Hi,
I'm seeing the same thing with a MacBookPro. When loading drm2 and i915
after boot, it works. I think it is something simple causing this failure.

Hi,
Can you try the attached patch. Works for me.
