[OT] Anybody using kernel 2.6.31

[john wendel]

I built 2.6.31 from kernel.org and I'm using it now on this F11 box. 
It's working OK, but when I get a lot of disk I/O going, I see laggy, 
jerky mouse movement. I've never seen this on a Fedora kernel or home 
built 2.6.30. I don't hear any audio problems like skipping, just bad 
mouse behavior.

Anybody have any suggestions for which kernel knobs I might tweak to fix 
this?

Thanks,

John
