In your case the entire machine became unresponsive? Are you running an RT kernel? I wonder if with RT and a high enough priority the jackd process could consume so much processor time that the system was not usable. In my case I have a kernel configured with preempt, but not the full preempt-RT patches. The only suggestion I would have is check whether the control-alt-F3 key combo can switch to a different virtual terminal, perhaps some process in the desktop environment locked up, but if you can get to a shell again you could kill jackd. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
