Created attachment 95042 [details] gdb backtrace from kwin with symbols Since I upgraded some packages (including Linux 3.13.2 -> 3.14-rc5, but not Mesa nor xf86-video-intel), I am unable to run KWin with desktop effects enabled. Daniel Vetter suggested in #intel-gfx that this may be buggy Mesa code that was triggered due to a change in 3.14, "enable[ment of] reset stat support". Distribution: Arch Linux x86_64 Linux: v3.14-rc5 Mesa: 10.0.3-1 kde-workspace: 4.11.6-3
we're now hitting this on Ubuntu since adding the separate i915_bdw module that needed some drm/i915 changes from 3.14 to build, namely drm/i915: add i915_get_reset_stats_ioctl drm/i915: add i915_reset_count so mesa 10.1 needs some backports from master?

so it's happening on 965GM, not sandybridge or broadwell at least
downstream bug says xorg-edgers build from git master is affected as well
i have problem whith my texture after updating linux karnel 3.14 i m runing mint 16 http://imgur.com/5pCfzOn http://imgur.com/1si6T86 http://imgur.com/UrBpTfy http://imgur.com/IQc2Txl any help for me i think that is rendering mode problem ?

domagoj: this is not your bug
ILK is indeed affected. I (OP) forgot to mention my hardware. Some more details: CPU: i5-460M (Ironlake GPU) libdrm: 2.4.52-1 libdrm master contains only some fixes for Freedreno, a FreeBSD platform fix and a change in the test suite. I believe that updating libdrm in Ubuntu won't help in this matter.

The problem disappeared with: KDE 4.13.0 Linux v3.15-rc1-356-gebfc45e Mesa 10.1.1 Not sure which of the three is responsible though.
Problem still exists in mesa-10.1.1 when not using the proposed patch, and it looks like master isn't fixed as well yet. Tested with: gentoo-sources-3.14.1 mesa-10.1.1 kde-frameworks-4.11.8 and kde-workspaces-4.12.4
I think you got your versions reversed. On this laptop, kdebase-workspace 4.11.8 (includes KWin) and kdebase-runtime 4.13.0 are installed. Perhaps you can try with a newer kernel?
Yeah, I got the KDE parts backwards... Anyway, kwin with kernel 3.15_rc1+ is just the same crash fest as 3.14 with vanilla mesa-10.1.1. Restored the mesa binary package with the patch, and everything's fine again. I guess Arch has you covered with the patch already?
yes, Arch has the patch, so no wonder it works for you: https://www.mail-archive.com/arch-commits@archlinux.org/msg169430.html
Indeed, I forgot to consider that possibility because Arch normally does not patch that much: https://projects.archlinux.org/svntogit/packages.git/tree/trunk/workaround-for-robustness-and-reset-with-intel.patch?h=packages/mesa
I'd love to see this one fixed, I also have an Arrandale/Ironlake (Core-i3 380M) laptop stuck at Linux 3.13 because of this bug... :/
I gave up on waiting and just pushed my original fix. commit 0380ec467d78f40b5c8134158ca48b4c5378b282 Author: Kenneth Graunke <kenneth@whitecape.org> Date: Wed Mar 12 01:43:40 2014 -0700 i965: Don't enable reset notification support on Gen4-5. arekm reported that using Chrome with GPU acceleration enabled on GM45 triggered the hw_ctx != NULL assertion in brw_get_graphics_reset_status. We definitely do not want to advertise reset notification support on Gen4-5 systems, since it needs hardware contexts, and we never even request a hardware context on those systems.

I have a doubt regarding this bug: I was one of the users who had this problem and with the first patch proposed (that got into Arch Linux fast) it got fixed. However, there's something strange: I use KDE with desktop effects turned on. For maybe a year or more before this bug happened I was using them with OpenGL 3.1 (in the System Setting -> Desktop effects -> Advanced you can choose that). When I upgraded to kernel 3.14 the desktop effects stopped working. Downgrading to 3.13 fixed it (and 3.14 + patch the same), but only if I selected OpenGL 2.0 instead of 3.1. Which is strange, because before upgrading it worked with OpenGL 3.1 normally, but after downgrading it didn't. Since then always the same, each time I try OpenGL 3.1 it breaks. And other users who suffered from this bug reported the same, OpenGL 3.1 didn't work for them either. I know it is a DIFFERENT BUG from this one, but I still wanted to ask if after kernel 3.14 OpenGL 3.1 works for anyone. And is there any other way of testing if it actually works other than in kwin? My graphics are Ironlake based (Gen 4?). Thanks.

Please open a new bug, I can confirm that KWin (kdebase-workspace 4.11.10) + OpenGL 3.1 + Linux 3.15-rc8 + mesa 10.2.1 + xf86-video-intel 2.99.912 crashes.
That new bug is probably https://bugs.gentoo.org/show_bug.cgi?id=513500

OpenGL 3.1 is not supported on Ironlake, so you shouldn't have 3.1 at all. The highest OpenGL version supported by Mesa on that chipset is 2.1.
