Simply using qjackctl's connections to feed usb midi um1 to my sw60xg (run as mpu401) to play some notes to compose a song. I have had the system freeze up a few times now doing this. Never happened before (and certainly do not require any real time capabalities to do this). Who gets the bug? And what info could I supply (since the system freezes, I have no log entries about this). Running realtime-lsm (I know it's obsolete but do not have rlimits available and do not know how to use it). Running "das-watchdog". This should have trapped any rt freezeup but maybe this does not work with rt preemptive kernels. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo.cgi/linux-audio-user
