Real-time kernels from the Ubuntu Studio Lucid repositories

[Mike Holstein]

interesting ralf... i wonder if thats just too new to work with
hardy/64studio... from what i remember, 64studio has an RT kernel already...
good luck getting an answer to this question, but i would wonder what in the
64studio repos would or would not work with the modern kernels....

just to be clear ralf, you are having these boot issues with 64studio? you
could try adding https://launchpad.net/~abogani/+archive/ppa to 64studio i
suppose, but when you look there, you can see there is an apt line for lucid
and maverick... theres probably a good reason why there is not one for
hardy...
