I am seeing lots of hard lock ups with Ubuntu Studio 9.04 too? I have seen it on two my computers and two of my sons. These machines are all different ages and have different hardware. We tried to debug it for a little while, but since it was happening on such a wide variety of hardware *and* since it was happening soon after boot up (i.e. no heavy processing, sometimes even before starting jack) we gave up? In fact, we are giving Arch Linux a try. We figure that if we have more control over the configuration that maybe we can (finally) get a stable / flexible Linux audio box? Don?t get me wrong ? we are big fans of Linux audio? but we want to spend ?some? time making music too? _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
