I once learned ( http://lkml.org/lkml/2008/2/29/179 ) that the CFS would have something to do with the latencies I was observing in my system if se.wait_max was bigger than 40 msecs. It would be an "anomaly" in CFS.
But in the log you uploaded you have only two se.wait_max greater than 40 msecs
[mafra@localhost:~]$ grep se.wait_max cfs-debug-info-2008.04.12-18.00.20 |awk '{ {if ($3 > 40.000000) print $3} }' 44.153039 50.841370
As these numbers are only a bit greater than 40, I guess your problem is not related to the CFS scheduler.
Can you try latencytop? ( www.latencytop.org )
Bye, Carlos
