After long discussions[1] at the german BSD-community we figured out that it seems to be a VIA-chipset based problem. # dd bs=1m < /dev/random > /dev/null does not slow down the system but with # dd bs=1m < /dev/zero > tmpfile the system becomes nearly unusable after some seconds. If I start mplayer to watch TV with my bt848-card the desktop environment freezes for round about 10 seconds before switching a windows or something like this. Any ideas how to fix this?
