I have been using the VooDoo_beta2 for a while and it has not fixed it for me. I still get mDNS responder errors too. I am running a 3.5ghz C2D with 4gb of 750mhz ddr2 on an ASUS P5N-t Deluxe mobo. I have also not yet tried the HT freq. x3 yet but will now. just letting you know that the kernel does not seem to be a total fix for everyone. cheers all~
