Just though I would add a comment that I am also seeing this behaviour. It
(might) be related to having a "post-up" command attached to the ethernet
configuration. Here is my interfaces file:
xfers ~ # cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

If I comment out my post-up line, I appear to get a reliable network
interface brought up at boot time, however, with the post-up line
enabled, I often see one of the slaves fail on boot.
