backtrace of X when it freezes none

Description Sergio Durigan Junior 2012-05-02 22:04:47 UTC 
Description of problem:


X server is freezing when I use scroll on Firefox.  Only connecting via SSH using another machine and issuing a `kill -9' on the X server "solves" the problem.

This problem happens randomly, sometimes I use Firefox for 2 weeks without problems, sometimes it freezes in less than 24 hours.

Version-Release number of selected component (if applicable):

xorg-x11-drv-intel-2.17.0-8.fc16.x86_64
firefox-12.0-1.fc16.x86_64

How reproducible:

As I said above, this problem happens randomly.  Nothing strange appears on /var/log/messages.

Steps to Reproduce:
1. Open Firefox
2. Use scroll until X freezes
3.
  
Actual results:

X freezes.

Expected results:

X should not freeze.

Additional info:

I can provide additional info if needed.

When this happens, can you ssh into the machine and attach gdb to the X server?  If so, where does the backtrace show you stuck?

Also, is there anything in /sys/kernel/debug/dri/0/i915_error_state when this happens?
Comment 2 Adam Jackson 2012-05-03 20:48:44 UTC 
Also, which gpu is this with?  The output from 'lspci -n -s 0:2' is sufficient.

Hi Adam,

Thanks for the reply.  This is the requested output:

00:02.0 0300: 8086:2a42 (rev 07)
00:02.1 0380: 8086:2a43 (rev 07)

In a moment I will try to cause X to freeze, ssh into the machine and run GDB as requested.

Here is the full backtrace of X when it freezes.  Also, /sys/kernel/debug/dri/0/i915_error_state doesn't show any errors.

Ping.

This issue has just happened to me.  Is there any other information you need for this?

Thank you.

There is a newer report with the same bug, with more useful informations. Also that report is for Fedora 17.
