Closing log file. This might be due to low memory, but I am not sure. I wasn't doing anything at the time when the error occured, just watching a youtube video without interacting with my machine. Maybe this is related? http://forums.fedoraforum.org/showthread.php?t=303183
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.
Created attachment 117298 [details] 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. But you are missing commit 41f401ae27ee753d66aae341be60b27167bc5b62 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sat Jun 27 20:24:45 2015 +0100 sna/dri2: Early return for empty DRI2CopyRegion which does prevent one related crash.
