I don't remember writing this 9 years ago. If I run into this again I'll
probably open a new request. Go ahead and close it...

Title:
  grub-mkconfig picks the wrong kernel.

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub-common

  I have separate root-partitions for trying out if I really want to
  upgrade or not. But I have a shared /boot partition to allow me to
  tell grub to boot the old or the new install.

  Currently "old" is jaunty, ia32. "new" is natty x86_64.

  Somehow I managed to get a 32-bit vmlinuz-2.6.38-8-pae kernel in
  there. Anyway, according to the config-making utility (which seems to
  be grub-mkconfig) overrides the x86_64 kernel vmlinuz-2.6.38-8 . So I
  wasn't able to boot my fancy new x86_64 kernel, and using the 32-bit
  kernel results in a messy hang (the kernel will use a 64-bit insmod
  executable to try to load the binfmt handler for the first 64-bit
  binary (I'm guessing /sbin/init ?)

  Workaround: I renamed the vmlinuz...-pae kernel to one version less,
  and then it lists the 64-bit kernel at the top.
