[Freeswitch-users] Kernel timer ...those with experience please ?

Hi all, I have very recent git (20th Nov 2011) on linode instance on Ubuntu 10.04, kernel 2.6.39. When alone in a conference, the music plays very neatly and clear. When another person joins the conference, then everything becomes distorted, cant even hold a simple conversion. Reading around, everyone attributes this to kernel timer. Could the kind experienced souls share their knowledge on kernel timer, how it affects freeswitch, and how best to correct it please. BTW, am considering during new image build with the latest kernel, will it help ? David Wafula
