Swappiness being ignored in kernel 2.6.28?

Since the update to 2.6.28 I noticed that my system was being less responsive, not much but noticeable. I looked at memory usage and noticed that the kernel swapped more than before. At the time I had swappiness set to 40 so reduced it, thinking that might help. However now swappiness is at 0 and the kernel still swaps when it doesn't need to.

I have 512 mb ram. Yesterday I had about 60% memory usage and ~40 mb was in swap, despite swappiness being set to 0. What's going on?

Re: Swappiness being ignored in kernel 2.6.28?

Huh, the problem seems to solved in 2.6.28.2 …

EDIT: Nope, still present. Especially when not using the Laptop for a while, the kernel swaps. At the time of writing 50% of ram full, 8 mb in swap with swappiness 0.

I noticed that the mouse cursor hangs for a fraction of a second when using the Laptop again after some time of not doing anything with it. Also yesterday when I finished watching a movie it took a few seconds before my desktop appeared again, the redraw was quite slow.

Hmm, maybe this is a problem with Intel's GEM and the new video-intel driver will solve it? *goes to AUR to build version 2.6.1*
I'll report back later.
