I'm using SCHED_4BSD. Hmm, I'm using just a GENERIC kernel with support added in for my sound driver and atapicam for K3b. SCHED_4BSD looks default in GENERIC: options SCHED_4BSD # 4BSD scheduler I've been trying this morning with no real disk I/O and just XMMS open. It's much better than if I did have a download/upload going using disk I/O or trying to read from a file on the drive, but still nowhere near perfect. Every minute I'll still hear a little skip or stutter in the audio, and still notice the mouse locking up a bit at the exact moment that happens. So you have no similar problems in -STABLE? How about when untarring a bigger file and playing audio? If not, then maybe trying STABLE on that other drive might be a good idea. The reason I wanted to see any changelog was to see if there is any changes to this part of the code at all before trying it, but file by file I would probably be lost since I am not a programmer. Thanks. -Mark
