Re: [LIP] 2.6.1-"kernel panic: init not found"

I dont think this is the right list, but anyways here
is what i think should help!
i think your root disk is on ext3, by default the root
disk with ext2 is recognized.The initrd image that you
are making should have ext3 modules in it

mkinitrd --with=ext3 initrd<blah>.img 2.6.1(or
whatever the kernel name appearing in lib/modules.

You might get an error with this saying the module
mbcache or something like that is not installed. if
you get that ..just append "--builtin=mbcache" with
the above commmand and use the same initrd that you
created...
