reportbug only refers to "the whole system"; not *every* whole system,
perhaps that should be clarified?
2 breaks the whole system renders the entire system unusable (e.g.,
unbootable, unable to reach a multiuser runlevel,
etc.)

I believe this message was the last message seen when I was using
config-2.6.36-trunk-sparc64 from experimental; I downgraded to 2.6.32-5
when my machine wouldn't boot.
