Intel ValleyView kms console lock up

Xdm isn't running, I don't boot to the GUI directly, so I tried killall xinit without the kern.kms_console=0. It hangs and then needs the big switch held to turn power off.

I have seen similar issues on my Acer C720 (haswell based). Could you run a test for me?
* comment out your kern.kms_console=0 line so the KMS console is enabled.
* Instead of rebooting or halting from X, as root do a 'killall xdm' to kill X.
This should return you to a KMS console.
* Then try rebooting / shutting down from the KMS console.
What I have noticed on my Acer is two things: First, sometimes when I start X up I get corruption and have to restart X to get rid of it. But if I kldload i915kms first and give the kms console time to initialize, and THEN start X up, I never get corruption. And Second, when I try to shutdown/reboot from X the laptop often locks up. But if I killall xdm (as root) to kill X and return to the KMS console, and then shutdown/reboot from the KMS console, it always works reliably.

My Asus (Intel N2830 @ 2.16GHz) needs kern.kms_console="0" now. Without this, exiting the X server will lock up tight requiring a long press of the power button. With kms_console off, it shuts down with a black screen on the way, but it shuts down ok!
It is running this snapshot: DragonFly asus 4.3-DEVELOPMENT DragonFly v22.214.171.1247.g27b6eee-DEVELOPMENT #0: Thu Jul 30 10:39:15 UTC 2015 root at pkgbox64.dragonflybsd.org:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64
The gui was installed with "pkg install xorg xfce4 xfce4-power-manager firefox", acpi_video is loaded and dbus is enabled.
