Errores

After first booting before building a new kernel image

VFS: Cannot open root device "302" or unknown-block(3,2)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block(3,2)

I found two posibilities:

* You don't have your root fstype loaded into the kernel

OR

* You are not using the initrd.img, to create one:
mkinitrd -o /boot/initrd.img-2.6.3 /lib/modules/2.6.3

then add it to your lilo.conf

Kernel Panic

/sbin/init: 431: cannot open dev/console: no such file
Kernel Panic - not syncing: Attempted to kill init!

Por alguna razon desconocida (algun upgrade) se cambio el device /boot/grub/menu.lst de hda2 a hda1 con cambiarlo se arreglo. Para esto hay que bootear con un INSERT o similar
