Can not boot with kernel from kernel.org

[liptaka]

Hi!

I installed fedora, and it works fine with its own kernel, 2.6.23.1-42.fc8.

I want to set up a network diagnostic server (npad) on the machine, and according to
the manual for npad does not work with the distribution kernel, a "new" kernel from kernel.org must be installed.

I downloaded kernel 2.6.18 from kernel.org, and compiled it with the config of the working kernel.

When booting the following errors occured:
...
No volume groups found
Volume Group "VolGroup00" not found
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc failed: No such file or directory
setuproot: error mounting /sys failed: No such file or directory
switchroot: mount failed: No such file or directory


my menu.lst:

title fedora (2.6.18)
root (hd0,0)
kernel /vmlinuz-2.6.18 ro root=/dev/VolGroup00/LogVol00 rhgh quiet
initrd /initrd-2.6.18.img


title fedora (2.6.23.1-42.fc8)
root (hd0,0)
kernel /vmlinuz-2.6.23.1-42.fc8 ro root=/dev/VolGroup00/LogVol00 rhgh quiet
initrd /initrd-2.6.23.1-42.fc8.img



Can anybody help, what is the problem?
thanks in advance,
liptaka

Well, there could be config differences that lead to this since the kernels are pretty different, but I think its more likely your initrd is just not right. There must be missing filesystem drivers in the initrd. You may want to try creating it again.
