Freebsd-11.2-p2/amd64: Black-screen freeze with base i915kms and xf86-video-intel
I need help getting Xorg working with the intel driver. Here is some info:

If I do anything much different than the following, I get a black-screen freeze,
no network, no interrupts, dead keyboard. Only way out is power-off/power-on,
followed by single-user boot and fsck.
kldload i915
startx
which gets X going, but it uses VESA, not the intel driver.
For examples:
kldload i915kms --> black-screen-freeze
kldload drm2; kldload i915kms --> BSF
Don't load either --> BSF (xf86-video-intel installed, no drm or 915
modules)
HOWEVER: Exactly once, I forgot to kldload any of drm or i915kms or i915, and
then ran startx, Xorg used the intel driver and it seemed to work OK. It even
loaded i915kms and drm2 by itself, as was shown by kldstat after Xorg had shut
down. It never did that again! Unfortunately I can't find the Xorg log I
think I saved!
Some more detail, for the case where Xorg uses VESA:
kldstat right after boot:
Id Refs Address Size Name
1 7 0xffffffff80200000 20647f8 kernel
2 1 0xffffffff82421000 1780 uhid.ko
3 1 0xffffffff82423000 2328 ums.ko
kldstat right after loading i915.ko:
Id Refs Address Size Name
1 13 0xffffffff80200000 20647f8 kernel
2 1 0xffffffff82421000 1780 uhid.ko
3 1 0xffffffff82423000 2328 ums.ko
4 1 0xffffffff82426000 6d44 i915.ko
5 1 0xffffffff8242d000 10708 drm.ko
kldstat after startx and then exiting X:
Id Refs Address Size Name
1 33 0xffffffff80200000 20647f8 kernel
2 1 0xffffffff82421000 1780 uhid.ko
3 1 0xffffffff82423000 2328 ums.ko
4 1 0xffffffff82426000 6d44 i915.ko
5 1 0xffffffff8242d000 10708 drm.ko
6 1 0xffffffff8243e000 7a2b8 i915kms.ko
7 1 0xffffffff824b9000 3f8cc drm2.ko
8 4 0xffffffff824f9000 1ed0 iicbus.ko
9 1 0xffffffff824fb000 e58 iic.ko
10 1 0xffffffff824fc000 1570 iicbb.ko
Note that Xorg loaded the last five itself.

I have posted text files from which I composed the above at:
http://home.hiwaay.net/~kdunn/dellox755-X-tests
I also tried to use drm-next-kmod, with much the same results, including the
immediate crash on trying:
kldload /boot/modules/i915kms
I'm not too worried about that, because the base i915kms and drm/drm2 should
work for such an old chip, according to the message that appeared when I
installed drm-next-kmod (and deinstalled when it made no improvement).
Please let me know what to try next.
