Since I upgraded my ubuntu instance from 8.10 To 9.04 with apt-get upgrade, the following message is displayed when I do not start the instance:

Gave up waiting for root device. Common problems:
-Boot args (cat. proc/cmdline)
-Check root delay = (did the system wait long enough ?)
-Check root = (did teh system wait for the right device ?)
-Miss modules (cat/proc/modules; ls/dev)
ALERT! /Dev/disk/by-uuid/acc3414d-926c-453c-b458-cf47088d77d2 does not exist. dropping to a shell!

Busybox v1.10.2 (ubuntu 1:1. 10.2-lubuntu6) bucket-in shell (ash ).
Enter 'help' for a list of built-in commands

I tried to use rootdelay = 80 to load partitions.
