You have been subscribed to a public bug:

I just installed Ubuntu 9.10 Beta using IA64 ISO to a external usb-
attached hard drive. (System already has a internal hard drive but can't
install anything on that one).

Installation process finished alright with default options, using entire
hard drive which was correctly recognized during installation.

When I try to boot the system, I get the usual GRUB menu with the
correct options (normal boot, failsafe, memtest, etc). However, after
choosing the normal boot the system exits to a busybox console giving a
similar error message as the one that follows:

Boot from (hd0, 4) ext3 682bc0ce-b500-488e-b36e-4bc7ad043776
Starting up...
Loading, please wait...
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 the system wait for the right device?)
 -Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/682bc0ce-b500-488e-b36e-4bc7ad043776 does not exist. Dropping to shell!

Busybox v1.10.2 (Ubuntu 1:1.10.2-2ubuntu7) built-in shell (ash)
Enter 'help' for a list of built-in commands.

Apparently, from dmesg output it only finds one hard drive (sda), which
seems to be the internal one. BUT it is capable of reading GRUB menu, so
at some point it actually recognizes external hard drive.

Workaroung of adding "rootdelay=90" at grub.cfg (remember it's GRUB2)
doesn't work, neither typing "exit" after a few seconds.

Will try to provide "dmesg", "uname -a", "sudo lspci -vvnn" on following

System is a Dell Latitude D630 with Intel Core 2 Duo CPU.
