Hi Marco,

Did you consider building your own kernel? I'm using self-built RT
kernels on Ubuntu 12.04 and that works great:
And are you using rtirq?
Alessio Abogani stopped maintaining th RT kernels for Ubuntu quite a
while ago. You might want to ask falkTX about the possibilities of
offering a raring RT kernel.
