Ok.

Ok.

Loading of the kernel and initrd - takes a while on external devices
with lilo. Maybe using Grub instead is worth a try.

Sorry no idea yet. Can you please provide me a screenshot of the
booting process where it hangs? (Please put the screenshot on a
webserver and don't send it directly to the mailinglist, either use
a public image service if you don't have webspace on your own or
please mail it to me off-the-list.)

Oh, and you might want to try to use root=UUID=... instead of
root=/dev/sd[a-z]... so you can make sure your system uses the
correct device for booting.
