sorry for all my comments, finally it was a hardware problem... I had the freezes with the live DVD too, but only on this machine. I tried it on an another PC with identical hardware and there were no freezes. Now I could find a PCI-Network adapter, and using it instead of the onboard controller I don't have the freezes anymore. Sorry for having trashed this thread.
