Title:
  Grub2: Unexpected floppy access during boot

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  Observation:

  During the startup Grub2 always accesses my floppy drive. This happens right after the start-message of grub, but before the appearance of the menu. 
  Directly after the very noisy floppy-access an error-message is shown wich says something like "bootdisk error". But this message appears only for a fraction of a second and is therefore difficult to read. Instantly after this message has vanished, the normal boot-menu shows up. 

  The boot process itself is not harmed, though.

  My System:

  I run a Karmic which has been upgraded from Jaunty. After the
  additional upgrade from Grub-legacy to Grub2 the problem occured.

  "/boot" and "/" are on separate md-RAID1 devices. In the BIOS-Setup
  boot from floppy is disabled.

  /boot/grub/grub.cfg:
