Maybe it is related to this as well (though it is marked closed?) https://bugs.freedesktop.org/show_bug.cgi?id=87207 That backtrace doesn't tell us anything. Try addr2line -e /usr/lib/xorg/modules/drivers/intel_drv.so -i 0x7fcfee8a69b4 > addr2line -e /usr/lib/xorg/modules/drivers/intel_drv.so -i 0x7fcfee8a69b4
??:0
Same thing for all each other address.

A different backtrace
I compiled the intel driver with debugging flags enabled. I saw another segfault, presumably due to the same cause as above. This line might be interesting:
Jul 22 16:26:35 myhostname /usr/lib/gdm/gdm-x-session[885]: (EE) __kgem_retire_requests_upto:3185 assertion 'tmp->ring == rq->ring' failed
Does this help at all?
That is quite suspect. Can you please extract the full Xorg.0.log? I am afraid I can't. The X server is apparently restarted a couple of times and I guess the lockfile is overwritten at some point?! The output is from "journalctl -xe". I'd be happy to provide you with the entire file, but that is about 5M in size... Is there anything else I can do? Try something like journalctl _COMM=Xorg (where that has to match the executable name used by X on your system). Created attachment 117299 [details]
Backtrace from Xorg
I was able to salvage some data like this:
journalctl _SYSTEMD_UNIT=gdm.service
This is from the second occurrence (at Jul 22 16:26:35). You can see that the server is restarted 10 seconds later.
Those logs are not complete and don't contain anything useful.
