(wich will results in a lot more xruns) Without the "-R" flag: (almost all the times ...) - jackd runs without locking up the machine until I try to connect any client. - after stopping jackd (Ctrl-C) without conecting any client, the machine dont behave correctly after this, for example when a 'A' key in the terminal I got any other character, programs does not start correctly, the machine does not shutdown correctly, but have not seen any "oops" (but maybe just a random coincidence ....) But if it's a spin_lock(...) problem why does not just lock up my machine in this case ? I would interesting to known what happens if someone else could try starting the jackd without the "-R" and latest ALSA CVS.
