[gentoo-hardened] kernel upgrade problems: bad page state

[Brian Kroth]

I started getting these messages after an upgrade from 
hardened-sources-2.6.20-r10 to 2.6.22.r8.  Nothing changed from the old 
config.  I just did "make oldconfig" and answered N to everything since 
they weren't relevant.  In particular, nothing in PAX or GrSec menus 
were changed, though whenever I get big nasty messages like this I 
suspect one of them.  Can anyone give me some direction as to how to fix 
this or what might be causing it?  I can post the full configs if need be.

Thanks,
Brian
