Yeah, that's not good. Thanks for reporting it. Am I correct in
assuming this only happened during one boot and you have not been able
to make it happen again?
Ideally we would want to see a trace from reproducing it without the
nvidia driver, because then we could get help from upstream.

We'll (manually) cc you on any mail that requires a response. If
you'd like to hear the rest of the chatter associated to a bug report,
you can subscribe to it following instructions from here:
http://www.debian.org/Bugs/Developer#subscribe
I'm leaving the oops unsnipped in case someone reading has a chance
to analyze it with scripts/markup_oops.pl.
Hope that helps,
Jonathan
