kernel-2.6.23.1-21.fc7 doesn't boot when I use the mount option "relatime" for the root filesystem in /etc/fstab. It complains about an unknown mount option when trying to mount the root filesystem. Finally booting stops with kernel panic.
kernel-2.6.23.1-10.fc7 works fine.
Does https://bugzilla.redhat.com/296361 (nash mount should support relatime) shed any light on the problem you're having? Particularly this comment[1]:

This is not directly dependent on kernel version, but on the mount options specified in /etc/fstab *at the time a kernel update is installed*.
I now know that relatime is actually the default now, so anyone encountering this can remove relatime from their /etc/fstab and rebuild the initrd for their kernel to avoid this bug (I still think the patch should be applied for safety), and still have / mounted using relatime.
To rebuild your initrd you can run: /sbin/new-kernel-pkg --package kernel --mkinitrd --depmod --install 2.6.23.1-10 after removing the relatime flag from /etc/fstab. (This is probably an overkill way of rebuilding the initrd, it may be sufficient to run: mkinitrd /boot/initrd-2.6.23.1-10.fc7.img 2.6.23.1-10.fc7 but I know the 1st command is what kernel rpm installs use).
