Hello, I am (still) running FC5 kernel-smp on a single-disk Fedora-only dual core system. I recently tried to install the non-smp kernel with yum (I wanted to try both version, selecting via grub at startup). Right after the update I took a look at /boot: apparently the original kernel files /boot/*smp AND the directory /boot/grub have disappeared... Could you please suggest corrective actions before rebooting the system? Would "yum upgrade grub kernel-smp" fix the problem? Thank you, SJ # uname -r ; yum --version 2.6.17-1.2174_FC5smp 2.6.1 # grep kernel /var/log/yum.log Sep 06 13:05:50 Installed: kernel-smp.i686 2.6.17-1.2174_FC5 Oct 02 14:38:55 Installed: kernel.i686 2.6.17-1.2187_FC5 # rpm -qa | grep kernel kernel-smp-2.6.15-1.2054_FC5 kernel-smp-2.6.17-1.2174_FC5 kernel-2.6.17-1.2187_FC5 # rpm -V kernel-smp missing /boot/System.map-2.6.15-1.2054_FC5smp missing /boot/config-2.6.15-1.2054_FC5smp missing /boot/vmlinuz-2.6.15-1.2054_FC5smp missing /boot/System.map-2.6.17-1.2174_FC5smp missing /boot/config-2.6.17-1.2174_FC5smp missing /boot/vmlinuz-2.6.17-1.2174_FC5smp # rpm -V grub missing /boot/grub # cat /etc/fstab /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot1 /boot ext3 defaults 1 2 devpts /dev/pts devpts gid=5,mode=620 0 0 tmpfs /dev/shm tmpfs defaults 0 0 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 /dev/sdb3 swap swap defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0
