FC4->FC5 kernel 2.6.17-1.2139 panic

[Alexandru Ciobanu]

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

        initrd /boot/initrd-2.6.16-1.2115_FC4smp.img

fstab:

/dev/cciss/c0d0p1       swap                    swap    defaults        0 0

Any ideas?!

PS: Clean FC5 install is not an option.
