X freezes when scrolling on Firefox
Last modified: 2012-07-27 16:02:50 EDT
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):
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
X should not freeze.
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?
Also, which gpu is this with? The output from 'lspci -n -s 0:2' is sufficient.

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.

This is the X backtrace when it freezes.
This issue has just happened to me. Is there any other information you need for this?
There is a newer report with the same bug, with more useful informations. Also that report is for Fedora 17.
