With Mesa 6.5.2, running a GL application (such as glxgears or mplayer -vo gl) results in the application segmentation faulting immediately. This only occurs when DRI is enabled. I cannot get a backtrace; running within gdb locks up X entirely and seems to screw up the video hardware state, requiring a reboot. Currently I'm using Xorg 7.1 w/the latest modesetting branch of the Intel X driver. It looks like Xorg 7.2 isn't yet official, I will see if this still occurs with 7.2 as soon as packages hit my distro (probably within a week). I will note that this is a major improvement over Mesa 6.5.1, where GL applications would crash with or without DRI enabled. :/ So at least it has gone from non-working to working but slow.

Are you making sure that Mesa builds with -fno-strict-aliasing? > I cannot get a backtrace; running within gdb locks up X entirely and seems to > screw up the video hardware state, requiring a reboot. Yes, you can't debug an X server from within itself, because gdb stops execution of the X server, which is what provides interaction with gdb... it should work from a remote login though.
Yes, I'm using the Mesa ebuild from Gentoo, which appends -fno-strict-aliasing to the set of flags (so the full CFLAGS when Mesa is built is '-march=nocona -O2 -momit-leaf-frame-pointer -fno-strict-aliasing'). I'll see if I can get a backtrace using a remote login.
The bug priority was upgraded (P2->high) with the bugzilla configuration change. I'm Changing the priority back to the normal one. Sorry for the spam.
Created attachment 10862 [details] X Log With me, happens the same, I tested with Ubuntu Feisty and Ubuntu Gutsy (Alpha Version)

Created attachment 10928 [details] X Log with debug mode What more info is needed on this topic? I have an Intel MB DG965SS with Core 2 Duo that I bought less than 3 months and I realy can't use it. I'm having problems that this topic describes well. I decided to buy Intel because this MB is marked as compatible on the site and the open source drivers. And more, it is not relative to this topic: my sound card don't work microphone. I'm very disappointed with Intel.
I'm not seeing this problem with upstream driver. Jack, could you try newer driver? Wagner, did you report this problem to Ubuntu? I believe Ubuntu has validated on 965.

But if you can test, It's easy to reproduce in Ubuntu (could be Live Tribe 5). In the screensaver preferences, try Endgame, just need less than 5 minutes to crash.
Wagner, the original reporter says it happens for "any GL application". Are you also in this status? e.g. running "glxgears" will also crash?

I run glxgears and don't crash. Sorry for the inconvenience. What should I do now? Report a new bug?
Yes, Wagner, please open a new bug.
I'm closing as I can't reproduce it and no feedback from the original reporter for long time. Jack, please reopen if you can reproduce it with the latest driver.
I can confirm as fixed with kernel 2.6.22.1, xf86-video-intel 2.1.1, mesa 7.0.1, xorg-server 1.3.0 At first glance, things seem stable and reasonably fast. Thanks for your efforts.
