mine is doing the samething after updating, i thought maybe it might be my system since i was having problems before the update but now that i have re done the system i know now that its sd. i also notice that the orginal post also had a VIA MII board mines and MII10000 board though, same drivers as the MII12000. i have also attached the log from my system.
I installed sd on my other computer and worked just fine its an dell inspiron 6000 runs great and really smooth. its just a bummer that i cant get it to work in my truck :-(
