Comment 32 for bug 219192

Arafat, it's quite simple actually. Just complete the steps you'd complete normally to run Ubuntu from a USB stick, and then replace the initrd.gz on your USB stick with the one posted above (one is for Ubuntu, the other for Xubuntu). That's it - bug solved/worked around :)

(The instructions were on how to create your own initrd.gz but since other people did that for you that's not necessary)
