I was. My two main problems were: (1) failure to acquire SCHED_FIFO and (2) frequent segfaults when calling pthread_cancel(). I have not seen either since I started testing with LD_ASSUME_KERNEL=2.4.19 set. Today, I've been testing with NPTL (using the env variable). That seems to work, too, on Debian. This is still without your patch, just JACK 0.98.3 from CVS. Is there something different about the Red Hat NPTL implementation? -- joq
