Tried the Fedora 17 Alpha release on a crash-and-burn x86_64 system…      Definitely alpha quality…    Biggest show-stopper was the weird behaviour of grub2 and dracut, which meant that only one of the kernel choices in the grub2 menu booted OK, but others got ‘lost’ and threw all sorts of worrying udev and ‘xxx not found’ messages, before hanging the system..   All had worked OK with F16..    Dracut crashes on shutdown, with a whole shedload of errors.     Not really worth wasting time on until more gets fixed…   May try again in a week or so’s time..    Yes, I am a masochist…
