kern/54180: xorg segmentation fault with drm
>Synopsis: xorg segmentation fault with drm

>Release: NetBSD 8.0_STABLE on amd64
NetBSD localhost 8.0_STABLE NetBSD 8.0_STABLE (MuDo) #0: Mon May 6 07:43:31 +03 2019 root%research.net.md@localhost:/root/OBJ/sys/arch/amd64/compile/MuDo amd64
After recent src changes (probably dated on 22-23 April 2019) related to drm, xorg starts as expected, but crashes a few minutes with segmentation fault.
I tried several different PCs and laptops (most of them have i915drmkms). My observations are:
- If drm device detected and used at boot time, xorg crashes.
- If PC doesn't have usable drm, vesa driver works well.
- If disabled drm at boot time ("userconf disable i915drmkms" for example) loaded vesa driver and works well.
Last portion of sample output of Xorg.0.log is below:

Boot NetBSD 8 built with latest source on a pc with i915 (or detected as i915) VGA chipset. Start startx and try to open some programs (I used xfce4, and thunar is enough for trigger this error).
At boot time:
Go to command prompt before kernel load.
> userconf disable i915drmkms
After login, you can use xorg as usual.
