### END DEBIAN AUTOMAGIC KERNELS LIST
so does anyone know what to do


p.s. I can still boot off my old 2.6.18 kernel

Most noticable is what's missing from the first stanza: no initrd line.

Did you make a new initrd for the new kernel? Or, did you just omit putting that line in the stanza?

no I didnt would that be a problem
