Subject: 2.6.24-git4+ regression

Hello,

I noticed short thread in LKM regarding "sched: add vslice" causes horrible
interactivity under load.

I can see similar behavior. If I stress both CPU cores, even typing on
keyboard suffers from huge latencies, I can see letters appearing with delay
(typing into xterm). No swap is used at all, having 1GB free RAM.

I noticed this bad behavior with 2.6.24-git[46], 2.6.24-rc8-git was OK.

My config is attached.
