Comment 18 for bug 76598

flai, could you retry with the Feisty beta release and see if you can still reproduce this?

I would prefer it if anyone else experiencing this problem could file a new bug at this point. This bug log has got pretty confused and there seem to be a number of different issues at work.

Most issues like this are going to be kernel bugs or conceivably udev bugs, although there's a slim possibility of an installer bug. These days, the installer's involvement in figuring out where to find the CD device is limited to a pretty thin layer over programs in udev that tell us the type of a device.
