Dmesg says: pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel dead I am used to this. I unload the sound module and load it again and the problem is solved. As the unloading did not work, I did this here: AMD620:///home/erich (root) > kldstat Id Refs Address Size Name The console hangs then in this state forever. I am not able to stop it with control C. What could I prepare if this happens again to help debugging? Erich
