Ubuntu fails to boot with UUID

[Mohamed Amine Ilidrissi]

When booting Ubuntu, an error message is shown that is like: "udevadm trigger is not permitted when udev is unconfigured".
After a little while, the system is thrown back at BusyBox, stating that it gave up waiting for the root device:

Workaround: change the grub line to say "root=/dev/sdaX" (where X is the number of the partition Ubuntu is in) instead of UUID.

Seems the error does not occur anymore with Natty 2.6.36. Closing this bug.
