Phenomenon: Without load gnomemeeting VOIP connections are fine. As soon as some load like a kernel compile is put on the laptop the gnomemeeting audio stream is cut to pieces and gets unintelligible . On 2.4.2x I don't get even the slightest distortion in the audio stream under load. I played around with different nice levels with no success. The problem persisted during the whole 2.6.0-test series no matter whether I used -mm kernels or pristine Linus kernels. Even when nicing the kernel compile to +19 the distortions start right away. I tried Nick Piggin's scheduler which fared slightly better after changing the nice level of gnomemeeting to -10 but it's still a far cry from the 2.4.2x feeling without any fiddling with nice values. Any hints where to start looking are greatly appreciated. Christian Meder -- Christian Meder, email: chris@onestepahead.de What's the railroad to me ? I never go to see Where it ends. It fills a few hollows, And makes banks for the swallows, It sets the sand a-blowing, And the blackberries a-growing. (Henry David Thoreau)
