  lilo loads wrong data for big initramfs (?)

Bug description:
  Binary package hint: lilo

  I just updated an x86-64 system from gutsy to hardy, and the boot of
  2.6.24-16-generic hung after the line

      checking if image is initramfs...it isn't (bad gzip magic
  numbers); looks like an initrd

  I was able to boot successfully with the old 2.6.22-14-generic
  kernel/initramfs left over from the gutsy install.  I checked the
  2.6.24-16-generic initramfs and gzip was happy with it (and it looked
  like a valid cpio archive after I tested uncompressing it).

  My system is using LVM on software RAID-1 and using lilo (version
  1:22.8-3.1ubuntu1 is installed) as a bootloader.  So either lilo is
  loading the wrong data into memory or the kernel has a bug in
  recognizing the initramfs.  Given that almost everyone uses initramfs
  now, while grub has largely replaced lilo, a lilo bug seems more
  likely to me.

  Based on <http://lkml.org/lkml/2006/9/24/50> I made the wild guess
  that I was hitting some lilo size limit -- and indeed, the 2.6.24
  stuff is slightly bigger than the 2.6.22 stuff:

      1743752  vmlinuz-2.6.22-14-generic
      1887736  vmlinuz-2.6.24-16-generic

  and

      8450482  initrd.img-2.6.22-14-generic
      8871664  initrd.img-2.6.24-16-generic

  regenerating the 2.6.24-16-generic initramfs with update-initramfs
  didn't help.  However, I tried installing yaird and built a smaller
  initramfs:

      2287987  initrd.img-2.6.24-16-generic

  and now I am able to boot into 2.6.24-16-generic with the same
  lilo/kernel.
