Yep, froze after about an hour or so.  Tried batchbuffer dump see attachment to subsequent post.
This is 2.6.33rc2 on i845G.

Preliminary steps:

sudo apt-get install intel-gpu-tools
sudo INTEL_DEBUG=batch /etc/init.d/gdm restart

then got the hang.

I tried this:

sudo mount -t debugfs debugfs /sys/kernel/debug
datestr=$(date +%Y%m%d)
mkdir dri_debug-$datestr
sudo cp -r /sys/kernel/debug/dri/0/i915* dri_debug-$datestr
sudo intel_gpu_dump > dri_debug-$datestr/intel_gpu_dump.txt
dmesg > dri_debug-$datestr/dmesg.txt
cp /var/log/Xorg.0.log dri_debug-$datestr/
sudo cp /var/log/gdm/\:0.log dri_debug-$datestr/gdm.log
sudo tar czf dri_debug-$datestr.tgz dri_debug-$datestr/

and got:

mount: debugfs already mounted or /sys/kernel/debug busy
mount: according to mtab, none is already mounted on /sys/kernel/debug

but it did create:

jerry@linux:~$ ls -l dri*
-rw-r--r-- 1 root  root  388052 2010-01-02 13:39 dri_debug-20100102.tgz

Of any use?  Anything else needed for next hang?

to be attached on reboot of hung machine since that's where the tgz is.

Can't get gdm going from ssh or from Crtl-Alt-F1 will cycle power.
