Bug#386468: mdadm: cannot mount root filesystem after upgrade (system unbootable)

[martin f krafft]

Hi Cyrille,

Sorry that you're experiencing troubles with mdadm. From what I can
tell right now, I don't think it's serious, so don't panic or
stress, we'll work it out.

also sprach Cyrille Bollu <cyrille.bollu at tiscali.be> [2006.09.07.2227 +0200]:

That's because you cannot just mount to /.

What do you have in your grub configuration as the root= parameter?

This may well be #386315, I am waiting for upstream to respond.

and should it not be? Can you please show me your /etc/fstab file?

Hang in there, we'll fix it.
