I thought 10-mouse-sysmouse.fdi was introduced exactly to solve this problem. Or is there something special about my setup (with sysmouse providing a potential ums0 and psm0 being controlled by synaptics)? This was quite hard to track down since no process showed up using the CPU. Only because I had read the commit message for hal and the thread in freebsd-gnome, I even tried to disable hald. Should mice be generally excluded from hal until the problem is really solved? Maybe I misunderstood something. Jan Henrik
