You could run the EFI elilo with "-v" to get more verbosity, but I suspect
that the kernel was loaded into memory fine, and just couldn't find a
console to talk to.

If you're using a serial console, you need to supply something like
"console=ttyS0" (i.e., by using "append" in the elilo.conf file
or using "elilo vmlinux console=ttyS0" at the EFI shell prompt).
The port defaults to 9600 baud; use "console=ttyS0,115200" or whatever
is appropriate if you're using a different rate.  If you're using a
serial console on an HP machine, make sure the EFI console input/output/
error paths contain exactly one serial device (this is configured from
the EFI boot manager menu).
