Hello, I am having some trouble with a PCI card; the trouble goes away if I reduce the PCI bus speed slightly (by reducing the FSB speed of my ASUS A7V mainboard from 100 to 95 MHz). The system (and the PCI bus) is not overclocked or in any other way non-standard; I suspect that some oscillator or something like that on the Adaptec is slowly breaking due to its old age.
Is it possible to modify the speed of the PCI bus in a running Linux environment? I.e., is there some command to temporarily reduce it and return it to its original value later? Thanks, Ekkehard
