I figured I'd stop here first, and didn't want to cross-post to CURRENT, but I'm hoping someone can offer a little illumination on a problem I'm having.
I'm running -CURRENT from Oct 8th (same problem on CURRENT builds from August to present) on a Dell Inspiron 4000 and ever since I switched from 4.5 when I'm listening to audio I get pops, crackles & stuttering. I first thought it might be an interrupt problem, but after running vmstat everything looks fine except that there are always 2-6 processes waiting for CPU time. This is odd, because top is always showing anywhere from 80-85% idle time. Any idea what could be going on? I've turned off most of the debugging in the kernel, so I'm pretty sure I'm not wasting CPU cycles on that (although, duh, I can't troubleshoot this now)...
