Re: [linux-audio-user] is RT-Preempt functional on x86-64?

I have been having exactly the same abrupt rebooting after compiling .13
with realtime patch (not yet working on PAM tweaks). I have googled for
possible conflicts with predetermined Ubuntu Breezy kernel config; I
would like to preserve as much original Ubuntu's functionality as I can
(at least for experimental purposes).

BTW 64Studio people has achieved .13 multimedia kernels; they do kernel
tweaking like butter (as seen at their dev's mailing list). Are these
guys using the Molnar + rt/PAM solution?

(Sorry, just can't do a complete installation of 64Studio now.)

thank you in advance,

José
