It is a known problem that reading i915_regs can cause a lockup on
some computers. This file has been removed in recent kernels. You can
copy the other i915 files by using
sudo cp -r /sys/kernel/debug/dri/0/i915_{[a-q],ring}* dri_debug-$datestr
instead of
sudo cp -r /sys/kernel/debug/dri/0/i915* dri_debug-$datestr

What would make life easier is if you found a way to reproduce the
freeze more quickly. There is a gnome-specific script that was good at
reproducing some freezes on 965GM a while ago. That could be a
starting point, but would require some research into how to automate
things in other WMs.

Otherwise, I'm a little bit surprised the xorg-edgers should make a
difference regarding this freeze. Maybe you could go back to
xorg-edgers and enable desktop effects there as well, then maybe you
can get a freeze and a nice bathbuffer dump.
