Haven't looked in some time, but last I knew, they don't ship both an amd and an intel kernel. They ship an "i386" kernel, which works for all x86 cpus, amd and intel alike, and they ship an "amd64" kernel, which works for all x86_64 cpus, amd and intel alike. This is the exact same thing as us shipping i386 and x86_64 packages, just slightly different naming (AMD originated the platform, Debian named their 64-bit packages accordingly). -- Jarod Wilson jarod@xxxxxxxxxx _______________________________________________ kernel mailing list kernel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kernel
