Yeah, back when I was looking into amd64 vs i386 version and had a thread going that you replied to, I checked out your website and saw your FreeBSD settings. :) I tried that device.hints setting on my backup Athlon XP 2000+ machine with just onboard sound and that seemed to make it worse. Maybe because it was crummy onboard. This machine runs an Audigy 2 Platinum. If it was just the sound doing this and not the mouse and display freezing as well as any video playing then I think it would be much easier to troubleshoot and pinpoint. I could try -STABLE on that spare hard drive though. Thanks. -Mark P.S. On an unrelated note, is there any "changelog" or anything for -STABLE to see what changes have been made?
