As the box is located on a location I have to drive to for an hour, I cannot disable USB in the BIOS that easy. The things I could do from here, I have done so far, meaning I unloaded the uhci and ehci modules, changed from an smp kernel to a non smp kernel and even to a standard 386 kernel, disabled apic and acpi, loaded eepro100 instead of e100 and unloaded the parport modules without any results. > > Since I see ide0 in your output check if you have set the right hdparm > settings for IDE.

I suspect the problems may derive from a buggy BIOS/mainboard. So far I have no more idead what I can do. If I don't get any other ideas to solve this from any of you, I will try to disable USB physicaly in the BIOS, but that will be my last resort.
