    I'm having the same problem with my laptop. It fails (if I remember
well) when checkig an <O2 Micro> device (probably my card reader, don't
know). When rebooting got to loader prompt, unload kernel and load
/boot/kernel.old/kernel. This arrises a few questions :

        1.- How can I install a custom kernel under a different directory
            under /boot. I did it, but I can't find how (google doesn't
            help)I did it. I think there's a define when installing the
            kernel.
        2.- nextboot allows me to choose a different kernel a give it
            options, but is it possible to make the changes permanent ?

   Well, now I'm csup down to current 18/04. Hope it will work :)

   Excuse me for the previous mail, that webmail I'm using is driving me
more crazy :)

   Greets,
