Subject: Possible bug, with extreme low latency audio.

Hello.

I have shaved a kernel for features I suspected to add to os-jitter, to  
get the lowest possible latency from it.
The kernel is 2.6.36-zen0
The .config is http://www.paradoxuncreated.com/tmp/.config

What happens is, if I set my audioapp, (renoise) to extremely low  
latencies, (96khz, 8 samples buffers x 2), the audio seems to be  
distorting and speeding up, while having periods of normal playback.

With other kernel configurations, I have just experienced, glitches, which  
is typical of buffer underruns.
This kernel config though, reduces the overall os-jitter, so I could push  
the latency much lower. However then I stumbled on this problem.

Best Regards,
Uwaysi.
