hm, those photos aren't terribly useful. They seem to be pointing at
the compaction code.
Maybe using the pause_on_oops kernel command line option
(Documentation/kernel-parameters.txt) will prevent the frist part of
the first oops from scrolling off the screen?

It's possible but I'm agreed that the photos aren't terribly useful. It
would be preferable to see the first oops where as this appears to be a
second or third oops.
Also, I note this is a Fedora kernel. Is the bug readily reproducible?
If so, would you be willing to verify the problem happens with 2.6.38.7?
What are the reproduction steps?
