Does acpi cause the change_page_attr oopses?
What caused the several different oopses which I got with Andrew's config? They were all inside the gregkh-driver-* series. (That test machine is running FC1, which doesn't run udev at all. Its BIOS is acpi-free).
Here's one: http://userweb.kernel.org/~akpm/s5000364.jpg
I didn't grab the others.

Tried Andrew's .config?

I can tell an enormous string of oopses when I see one ;)
I'm dropping acpi and gregkh-driver-* and am rushing rc4-mm1. Other people's stuff needs to get tested.
