causes nightly and mesa-7.11 to crash

This machine has an intel i865 GPU
about:support loads fine with an intel i915g GPU which is the next generation intel GPU
I'll link to this report when I file a bug at freedesktop.org  mesa-7.11

I finally booted Debian stable and tested using kernel 2.6.32-5-686, mesa 7.7.1, firefox 10-0a1
mesa 7.7.1 is working correctly and loads about:config with all fields filled in.
http://get.webgl.org is also not crashing as reported above ( but is not loading webgl content ) when running kernel 3.1.0-1-686-pae, messa 7.11, nightly 10-0a1

Debian Stable - kernel 2.6.32-5-686 - mesa 7.7 - firefox8 10 and 11 
load about:support 
all fields are filled in and both buttons ( Copy all to clipboard and Open Containing Folder) are working.

see bug filed for mesa 7.11 
https://bugs.freedesktop.org/show_bug.cgi?id=42611
Debian Sid - kernel 3.1.0-1-686-pae - mesa 7.11 - Firefox 10

I hope this comment explains a bit better than comment 1.

Closing:
The hardware spec does not meet the minimal required for the QA test case.

4. Linux-x11 machine that supports OpenGL layers.  Latest Ubuntu release + NVIDIA GPU and proprietary NVIDIA drivers is usually the most reliable combination, sadly.

In that order of importance.

(It would be useful at some point to check a machine without GPU layers, but the benchmarks below are so slow without GPU support that it doesn't really matter.  Plus the non-GPU path is what we've been optimizing in fennec for the last year.)

Will, i don't know if you are a Mozilla developer, but i'm really concerned with the reason why you closed the bug.

Please, can you point me to a document that help me to understand how can i check if a specific graphic card supports opengl layers?
Firefox's release notes doesn't mention that requirements: it's weird that a user have to discover an hardware requirement looking through a bug report. If #692989 is so normative its content should be incorporated in the release notes.

And, also, i find that a crash is a discutible reaction to an unsupported condition (that the user can't check himself). In a well written software i call it a bug.

Cesare.

Please try mesa  7.11.2-3. My FC16 machine with i865 displayed the same crash in Firefox with mesa  7.11.2-1, and since the update no longer does so. I also added a new user which may be co-incidence.

Here is earlier Firefox crash report:

https://crash-stats.mozilla.com/report/index/bp-9b9e53cf-7bab-462c-b8ae-b1bd32120301

As per comment 6 I am no longer able to reproduce crash on my machine with i865. However I have a similar machine with i845, with same FC16 and also mesa 7.11.2-3, this still crashes in Firefox on about:support and any WebGL page. I see this will be fixed with https://bugzilla.mozilla.org/show_bug.cgi?id=696636, which will force WebGL disabled if OpenGL <2.

Apolgies - just checked and I had set Firefox setting 'webgl.disabled userset true' on the i865 machine, please ignore above two comments. I understand this what the https://bugzilla.mozilla.org/show_bug.cgi?id=696636 will fix.

Thank you very much John!
I didn't know the webgl.disabled setting: that solved my crashes on a number of sites (now only two tested). Great workaround waiting for #696636 fix (i855 here).
