The kernel starts to load, but panics because it is unable to find the
root partition. When it stops it shows the available partitions, these
include all the hard disk partitions but no USB key partition. In fact,
if I omit the 'root' parameter from the grub shell the boot works fine
but it uses the hard disk root partition instead of the USB one.
You may want to look at specifying root by it's UUID. This will prevent
issues like the USB drive being /dev/sdg on one machine, /dev/sdb on
another, and on reboot it all changing because the drives were detected
in a different order.
From the log on the screen the USB controller seems correctly detected,
so I don't understand why it is not finding the root. While writing this
one idea comes to my mind, maybe it is failing because I attach the key
to a SDC/MMC/USB card reader? This evening I'll try to plug it into a
different USB slot.
In the past, instead of 'rootdelay=', I add a wait to the init script, eg:
while [ ! -e /dev/disk/by-uuid/1234-abcd-45gf-0659 ]
do
sleep 0.1
done
