Title:
  unable to mount root fx on unknown-block(0,0)

Status in “grub2” package in Ubuntu:
  Expired

Bug description:
  I installed the karmic beta on my netbook and all was working fine.
  Today I did an update, after which ubuntu failed to boot with the
  error "unable to mount root fx on unknown-block(0,0)". Replacing the
  root=UUID=... linux parameter with root=/dev/sda1 made the os boot
  again.

  The UUID in /boot/grub/grub.cfg matches the UUID in /etc/fstab and the
  output of "ls -l /dev/disk/by-uuid/".
