oh, software enviroment is same :) just i had compile kernel for MB

Still, VIA controllers are known to be buggy and VIA is not willing to work with us to try to fix issues like this. The bugs can be caused by timing issues, so they might not show up on other hardware.

There's really not much we can do here about this, I'm very sorry.
