As Tim indicates there is an element of a race to this issue.  On my
test system and upgraded (Maverick -> Natty) system the issue was not
reproducible in 20 reboots.  I scratch installed from the same Natty
image and the issue was instantly reproducible.  In testing removing the
ureadahead pack seems to render the machine bootable for the next boot.
All of this tends to indicate that this is indeed a boot race.

It is reminicent of the framebuffer open races we experienced in
Maverick.  Cirtainly in boots where things work there is no sign of the
vesafb being used, whereas it appears to be painted by plymouth in most
of the failed boots.
