Hi Eric

Ehhmmm, I'm afraid, I don't know, if I have any closed-source BIOS code
randomly stomping over my chip's state. 

Actually, I just have installed Sidux (a SID derived distro) from its
installation DVD. I needed to upgrade the intel driver to the experimental repo
(this was a tipp from thinkwiki) to get it working with the graphics chip.

In general, all works great with 2.6.27.7, including suspend to ram. The only
problem I have is with the iwlagn driver which has a bug when lots of data is
transferred. I read that the bug is solved in 2.6,28. That's why I have tried
to install 2.6.28, which however lead to the above problem.

So, how can I find out if there is any userland code POSTing the chip after
resume? I have done a "lshal|grep quirk" with no output.

I can post the output of cat /proc/dri/0/i915_gem_interrupt, if that helps. I
have no idea, however, how to make a backtrace.

Sorry, that I am not of much help.
