Sounds like a problem with the initial ramdisk. Sense you said you had
to add the new kernel to the boot menu, I deduce that you didn't do the
install properly (or you forgot ramdisk support in the kernel config).
Remember that you need ramdisk and initial ramdisk support in the new
kernel. I learned this the hard way!
I just built 18.104.22.168 with the following procedure:
 download linux-2.6.11.tar.bz2 and patch-22.214.171.124.bz2
 tar --bzip -xf linux-2.6.11.tar.bz2
 bunzip2 patch-126.96.36.199.bz2
 mv patch-188.8.131.52 linux-2.6.11
 cd linux-2.6.11
 make mrproper
 patch -p1 < patch-184.108.40.206
 cp /root/config.2.6.11 .config
Where I keep my config file. Yours is probably somewhere else.
 make oldconfig
You can replace [8,9] with make menuconfig or your favorite variation if
you don't already have a saved config file.
[B] make modules_install
Gotta do this before "make install".
[C] make install
You don't have to add anything to grub.conf, "make install" did it
already. And it installed the initial ramdisk.
I usually edit grub.conf to remove the previous kernel, just keeping the
new one and the latest Fedora kernel in case something is broken in the
Hope this helps.
