Subject: Scheduling problems ? [ Was: Linux 2.6.26-rc1 ]

Hi...

I have installed this kernel, and it behaves a bit strange.

If I launch a movie under totem, it plays nicely (no HD, just 512x384).
If then I start deluge with some torrents downloading, the video begins to
loose frames and jump, like loosing 1 or 2 frames per second.
There is not much bandwidth used, just 15-20 Kb.

I have tried the same copying a kernel source tree and the video plays fine.
So can it be something network related, os network+io to disk ?

No group scheduling, 1000Hz, fully preemptive kernel.
If you smell something and need my .config I will post it.

TIA
