F8 does not boot new kernel

[Alard]

Hello all

I have a problem with booting my box after yum update kernel.
First of all, new kernel does not appear in grub menu. I've added it manually, but when i try to boot from new kernel, i have some errors:

"Bad magic number in super-block while trying to open /dev/sda1

The superblock could not be read or does not describe a valid ext2 filesystem.
If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else)? then the superblock is corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 /dev/sda1

/boot: clean, 36/2608 files, 22125/104420 blocks"

/dev/sda1 contain my boot partition

BUT when i rty to boot with my old kernel, everything is ok, fedora boot with no errors.

Can someone help me?

Thank you.

My system is F8_x86-64

Build your kernel on your own hands, that is not so hard as it looks.

build your new kernel with no-initrd option, that what i did, and doing.
