You are using vesafb. This is a bad idea. Disable vesafb. Even through KMS drivers support vesafb handover, this is known to cause instability. If the problem remains after removing vesafb from your kernel: Please also report this upstream on https://bugs.freedesktop.org/ (if no report already exists) and provide a link to the bug report here.
From my kernel .config: # CONFIG_FB_BOOT_VESA_SUPPORT is not set # CONFIG_FB_VESA is not set How can you say I'm using vesafb?
From your Xorg.0.log > [ 19.907] Kernel command line: root=/dev/sda3 splash=verbose video=vesafb:mtrr,ywrap But if vesafb is disabled in your kernel, then that cannot be the cause of your problem.
Actually I downgraded to x11-drivers/xf86-video-intel-2.16.0 and no segmentation fault happened for more than 4 hours
No more segmentation for 2 days, so the problem was related to x11-drivers/xf86-video-intel-2.18.0, downgradind to x11-drivers/xf86-video-intel-2.16.0 solved it.

I`ve had some other issue with 2.18 as well, but this is maybe somehow connected to https://bugs.freedesktop.org/show_bug.cgi?id=46684#c22, (that specific commit).

(In reply to comment #11) > (In reply to comment #10) > > ... > > Sry, i`m still half woken up. I meant, it would be worth trying this patch > mentioned in upstream bug report I've opened an upstream bugreport: https://bugs.freedesktop.org/show_bug.cgi?id=47639 As I undestanded, if the patch you suggested is in mainstream git repository, actually I'm testing a git build.
Since when I started using the git build I had no segmentation faults, so I can say the problem is solved in git sources.
Assuming the fixes for your issues are now available in newer releases, closing fixed. Please don't hesitate to reopen this bug if not. Thanks
