Troubleshooting kernel package installation

If after applying my kernel 2.6.9-89.0.20 package the lcd shows 'IP Address not set' , there is a failure in the upgrade installation. This is because yum had installed newer kernels and the rpm software don't want to install the rpm included in this package.

1.- To repair it you need to boot the server with a terminal connected to the serial console port. When the message 'Press spacebar to enter ROM mode' appears, press the space bar.
2.- Once in the ROM menu type 'bfd /boot/vmlinux_old_002.bz2'. This command forces to boot from the old kernel.
3.- Login to the server as root.
4.- # cd /boot
5.- # rpm -i --force http://www.titox-net.es/downloads/cobalt/BlueQuartz/kernel/linux-2.6.9-89.0.20-cobalt/kernel-2.6.9-89.0.20_cobalt.i386.rpm
6.- # ln -s vmlinux-2.6.9-89.0.20.EL-cobalt.bz2 vmlinux.bz2
7.- # reboot

There is a mistake in the kernel config and RAID devices are not working... OK I will compile a new version soon as possible, I need for my new server!!!!!!! Sorry guys.
