With lockup bugs, usually what's happening is the GPU has hung due to some bad register setting.

There is a tool for taking a snapshot of the GPU's register settings, `intel_reg_dumper`, which is available as part of the xserver-xorg-video-intel-dbg package. So install that, and then run this tool in two cases:

1. With the display working properly

 sudo intel_reg_dumper > reg_good.txt

2. After reproducing the lockup (you'll need to ssh into the box from a 2nd machine):

 sudo intel_reg_dumper > reg_bad.txt

Then attach both files to this bug report. We can send the report upstream for there to see if a fix can be identified.
