dmesg is attatched here.
dmesg shows that the freeze is caused by mutex lock.
It may be caused by below sequence.
1. mutex locked and not unlocked.

I rebuild the kernel with debug enabled.
And I tried to investigate the freeze problem.
But, kernel configuration(attached with this post) works fine.
I couldn't reproduce the problem with the kernel.
There might be some problems with lock sequence of the intel driver.

I install the latest drm-intel-next kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/2010-02-24/ .
And I got batchbuffer dump.

I don't use Lucid for now. So I build patched libdrm for my karmic.

I have uploaded an older version of mesa to my old PPA:

we can find out if this is caused by a bug in mesa which is introduced
after version 7.5.
Geir, I tested the older mesa package, but I got freeze.

I executed apport collect 475429. ( with Lucid normal kernel )

So, the dump I
If you can also get the batchbuffer dump, that would be nice.
The batchbuffer is attached in #37.
It contains batchbuffer except i915_regs file.
I think that there is no problem because the i915_regs file is disabled by the

I tested Lucid and Lucid+xorg-edgers.
( Lucid install xorg-edgers ppa to sources.list apt-get upgrade )
Both of them have same problem.
I tried to get batchbuffer dump, but I couldn't it.
The reason is that, the lucid kernel hangs up during sudo cp -r

From 2009-06-19a, 3D graphics performance is greatly improved.( glxgears fps
increased 500 to 2000. )
I think that, the improvement is because of direct rendering.

First time, I tried that, but it has not improved in my environment.

compiz can disable the direct rendering by the checkbox.
