This bug was fixed in the package udev - 173-0ubuntu4.1
---------------
udev (173-0ubuntu4.1) oneiric-proposed; urgency=low
[ Andy Whitcroft ]
* debian/udev.initramfs-bottom: ignore timeout errors from udevadm we
expect (and indeed requested) in certain failure modes. If we do not we
will bail out early and not transfer /dev into /root which is always
fatal leading to unbootable machines. (LP: #818177)
* avoid-exit-deadlock-for-timely-events: avoid deadlock when exiting
by continuing to handle events with timeliness requirements.
The timeliness requirement will be violated if we ignore them which
is highly undesirable. Also these events are typically dependant
events and may well block the events we are waiting on leading to
boot delays and uninitialised devices. (LP: #842560)
* debian/udev.initramfs-bottom: increase the client-side timeout to
better cope with potential timeout extension issues in udev. We very
much would prefer udev to time itself out and guarantee to have
completed than take action ourselves. Very worst case the timeout may
be doubled from the default of 60s so increase ours accordingly. Note,
we should only ever trip this timeout when we are already in severe
trouble. (LP: #818177)

Bug description:
After running a do-release-upgrade -d on a natty server, I'm unable to
boot the machine properly.
It looks like it doesn't see the local disks anymore.
I think this looks quite a lot like the debbug linked from here:
