Bug Description
I just upstreamed the bug report below (opening this bug just to track it in ubuntu).
*******
Just now I started Firefox and my xserver froze. I grabbed a backtrace from gdb
and X was stucking waiting for some ioctl(). I also took a copy of xorg.lorg
which contains a "xorg is probably in an infinite loop backtrace" as such:
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Previously when I used 2.6.27 kernel with intel 2.4.1 I never saw this
particular freeze at all.
When I upgraded to jaunty I got 2.6.28 kernel and intel 2.5.1 I run into this
problem.
This bug is not reproducible by specific steps though, it just happens at
random times out of the blue. If you have additional info you need I can write
it down on a post-it next to my machine and try to collect that data once the
bug happens to be triggered again.
My hardware is a x64 box with intel g45 (some lines from "lspci -nn" below):
00:00.0 Host bridge [0600]: Intel Corporation 4 Series Chipset DRAM Controller
[8086:2e20] (rev 03)
00:02.0 VGA compatible controller [0300]: Intel Corporation 4 Series Chipset
Integrated Graphics Controller [8086:2e22] (rev 03)
00:02.1 Display controller [0380]: Intel Corporation 4 Series Chipset
Integrated Graphics Controller [8086:2e23] (rev 03)
I have "current jaunty versions" which right now means:
ii libdrm-intel1 2.4.1-0ubuntu7
ii xserver-
ii linux-image-
ii xserver-xorg 1:7.4~5ubuntu5
ii libgl1-mesa-dri 7.2-1ubuntu2
