>Description:
After upgrading via the sets available from releng builds from
July 16th (http://releng.netbsd.org/builds/HEAD/202207160630Z) I'm not
able to start X on amd64 with i915 graphics, using the modesetting driver.

If I move my xorg.conf out of the way and let X choose its default
(intel instead of modesetting), then it does start and run without
issue. (I'd understood that modesetting was now recommended over
intel?)

It's possible that the "Unknown vendor-specific block 0" output has
some relevance here.

Full Xorg.log follows.
