Hello, I'm back with my old distribution and I decided not to touch it anymore ... I will install RT with a more recent distrib in a separate computer. Please can you advise me the most appropriate recent distribution to use the RT kernel and comedi drivers ? (if you have a step by step installation of the RT kernel, it would be perfect !)

It was not working (it was frozen at the login stage ...).
