Hello, I'm trying to upgrade my FC3 dual cpu server to FC4 as it described at http://fedoraproject.org/wiki/YumUpgradeFaq. To avoid 'kernel requires kernel-utils (or vice-versa)' problem I did yum update kernel-smp reboot and I got: mkrootdev: label / not found mounting root filesystem mount: error 19 mounting ext3 mount: erro2 mounting none switching to newroot switchroot: mount failed:22 umount /initrd/dev failed: 2 At this point, the server kernel panicked. The old one (2.6.11-1.27_FC3) still boots correctly!
