[ Just adding a lot of other people to the cc ]

Robert, could you add a dmesg of a successful boot to that bugzilla,
or just as an attachement in email to this group of people..

This looks to be with the Fedora kernel config. Two people reporting
it, it looks like similar machines.

I assume it's some odd memory sizing detail that happens to trigger a
particular case.

I absolutely *hate* those "let's lazily clear 'struct page' array"
patches. They've caused problems before, and I'm not convinced the
pain has been worth it. Maybe we should revert them (again) and
promise to never ever take things like that again? Andrew?
