While booting F10 Alpha on a IBM Power5 ppc LPAR, I see the following kernel message during boot. This message does not appear to negatively impact the bootup, as the system proceeds into the installer.

James, this should be fixed in Fedora 10 Beta with kernel 2.6.27-0.352.rc7.git1.fc10. *** This bug has been marked as a duplicate of bug 458500 ***
