Bug#594472: grub-pc: scary messages and very long boot time after upgrade

[Dh H]

Downgrading MDADM helped for me, but not completely.
The behaviour at the beginning is still the same, such that it does
not find the volume-group.
But now I am dropped into a shell instead of getting these
/sys/devices/virtual/block/mdX
messages.

In that shell I can use lvm to bring the vg up and activate the lvs.
from that point on booting works fine.

Toni, I used this link to get mdadm for downgrade:
