Description Mikolaj 2019-10-17 13:10:31 UTC
I'm failing random Xorg crashes where I suspect intel_drv.so as the culprit. It happens on the Xorg start or often triggered by GIMP start or open file dialog in GIMP.

My system is Huawei MateBook X with Intel HD Graphics 620 running on OpenBSD:

OpenBSD 6.6-current (GENERIC.MP) #378: Wed Oct 16 23:06:01 MDT 2019
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

I've compiled commit bff5eca49b27cb47673123222a714d2a6f56287f from https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel.git with --enable-debug=full option and during crash I see following in Xorg.0.log:

I have couple of logs like that. I've compressed them with xz(1) however there are max 10MB each.

This is one of the log files which I have when Xorg dies. All of them have following line:

Comment 2 Chris Wilson 2019-10-17 13:17:01 UTC
Looks like the BSD kernel driver does not conform to the uABI of i915.ko.
Comment 3 Mikolaj 2019-10-17 18:22:17 UTC
I've also reported this on OpenBSD side:
