SuSE9.2 - kernel: Losing some ticks...checking if CPU frequency changed.

Hello List, i have a K7S8X ASROCK motherboard, 256MB ram and an AMD Duron 1.6Ghz. When i try to install suse9.2 from a FTP-DVD, i get this error on tty4 and it freezes: kernel: Losing some ticks...checking if CPU frequency changed. I have already tried apci=off and SafeSettings. Then i loaded the default Bios settings, and took out my PCI modem, disabled onboard Audio and Lan. Memtest ran 12h and its ok. Has anyone ideas how i could solve this?! FTP or NFS install freezes with the same error. Thanks a lot, Mario
