I'm trying to use an Audiotrak OptoPlay usb audio device, one that appears as supported hardware in the handbook, in conjunction with mplayer. It works great for tens of minutes and then it forces a reboot leading the the following snippet in /var/log/messages: > FreeBSD 5.4-RELEASE #3: Sat Sep 24 16:54:39 EDT 2005 > ugen0: Ego Systems Inc. AUDIOTRAK OptoPlay, rev 1.00/1.00, addr 2 > WARNING: / was not properly dismounted > WARNING: /tmp was not properly dismounted > WARNING: /usr was not properly dismounted > WARNING: /var was not properly dismounted > ugen0: at uhub0 port 1 (addr 2) disconnected > ugen0: detached > uaudio0: Ego Systems Inc.

No dump device defined. > Automatic reboot in 15 seconds - press a key on the console to abort I've done some research that has pointed at pcm and snd_uaudio things, but I haven't found anything conclusive. The warnings above are probably related to the machine coming down hard since this log is from the second time the machine automatically rebooted. I appear to have a memory leak, but I was wondering if others on this list had some pointers. I wanted to try rebuilding a kernel from the stable branch, and I wanted to apply the patch found at http://staff.mybsd.org.my/skywizard/FreeBSD/sound/, but everything I've read has mentioned to rebuild world if I change from release to stable. This machine needs to be production quality, so I'm wary as to which course of action to take. Thanks in advance, Steve
