Hi everybody, I did an upgrade from FC4 to FC5 yesterday. After booting into FC5 kernel 2.6.17-1.2139_FC5smp freezes. I get these errors: >Mounting root filesystem >mount: could not find filesystem /dev/root >Setuproot: mouting /dev failed: No such file or directory >Setuproot: error mounting /proc: No such file or directory >Setuproot: error mounting /sys: No such file or directory after which I receive a kernel panic. Steps I've made so far trying to fix this: 1. making a new initrd with mkinitrd. No help 2. Edited the nash init script: > mount /sysroot replaced with >mkrootdev -t reiserfs -o defaults,ro /dev/cciss/c0d0p2 where /dev/cciss/c0d0p2 is my / My grub.conf: default=1 timeout=5 title Fedora Core (2.6.17-1.2139_FC5) root (hd0,1) kernel /boot/vmlinuz-2.6.17-1.2139_FC5 ro root=/dev/cciss/c0d0p2 initrd /boot/initrd-2.6.17-1.2139_FC5.img title Fedora Core (2.6.17-1.2139_FC5smp) root (hd0,1) kernel /boot/vmlinuz-2.6.17-1.2139_FC5smp ro root=/dev/cciss/c0d0p2 initrd /boot/initrd-2.6.17-1.2139_FC5smp.img title Fedora Core (2.6.16-1.2115_FC4) root (hd0,1) kernel /boot/vmlinuz-2.6.16-1.2115_FC4 ro root=/dev/cciss/c0d0p2 initrd /boot/initrd-2.6.16-1.2115_FC4.img title Fedora Core (2.6.16-1.2115_FC4smp) root (hd0,1) kernel /boot/vmlinuz-2.6.16-1.2115_FC4smp ro root=/dev/cciss/c0d0p2 initrd /boot/initrd-2.6.16-1.2115_FC4smp.img fstab: /dev/cciss/c0d0p2 / reiserfs defaults 1 1 /dev/devpts /dev/pts devpts gid=5,mode=620 0 0 /dev/shm /dev/shm tmpfs defaults 0 0 /dev/proc /proc proc defaults 0 0 /dev/sys /sys sysfs defaults 0 0 /dev/cciss/c0d0p3 /var reiserfs defaults 1 2 /dev/cciss/c0d0p1 swap swap defaults 0 0 Any ideas?! PS: Clean FC5 install is not an option. TIA
