Copy of issue 971

grml iso is not found when /boot is located on /dev/md0.

Fresh install of Debian Wheezy. /boot is located on /dev/md0, a RAID1 device 
located on /dev/sda1 and /dev/sdb1. Error message depends on the grml iso used:

grml-2013-02 fails with "mount aufs on /root..." message and drops to initramfs 
shell. /dev/md0 is not mounted.

grml-latest-testing (2013-09-04) drops to an initramfs shell too, but here /dev/
md0 is mounted. It looks like here only the timeout before it drops to a shell 
is too short.

Screenshots with all error messages attached.
