we dont really ignore it - we detect that it got corrupted by the
bootloader. (it got overwritten by the kernel image - information has
been destroyed irrevocably)

how we react to that breakage we detect is up to debate: it's fine to
try to continue (presumably a huge vmlinux means it has all the drivers
already) - and if a system relies on an initrd it wont get fast in
bootup anyway.

that's why i suggested to print a warning, do a 5 seconds delay after
that warning via mdelay(5000) so that the user has a chance to notice
what is wrong, and then try to continue. Panicking is just as fine.
