[Bug 353898] Re: [i945GM] Display locks-up in various circumstances

[Bryce Harrington]

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.
