F17 alpha install halted - DVD image on USB

[Frederic Muller]

Hi!

Downloaded F17 alpha and used livecd-to-disk -format --reset-mbr to 
generate a bootable USB disk. The disk boots and halt in the following way:

I took a look at current know issues (like not being able to install on 
an already installed system) and did a quick google search on the last 
error message without any much luck.

Is this a new problem (and I'll happily file a bug) or a know issue 
which I failed to find?

Thanks a lot.
