Computer without floppy drive are quite common.
If the floppy controller is enable in BIOS (which is often the default
configuration), anaconda hangs during the "Finding storage devices" stage.
I don't see this bug is a blocker for the release, probably should be.
Remi.
P.S. I don't think I'm a noob, but I have to search for this issue...
