Maybe you want to try a little IO latency measurement program to see if the skips are beeing caused by disk/ioscheduling delays, it's in:
http://pedro.larroy.com/devel/iolat/
Here: http://pedro.larroy.com/devel/iolat/analisys/ are some measures from an ide disk in a AMD-768 chipset and a scsi cheetah 10K on an AIC-7892A U160/m.
I'm still working to find why those delays in the ide disk.
