Hmm. Any chance the order of module loading changed between the two versions? I see you have 'psmouse' as a module. If i8042 (and psmouse) are loaded after uhci-hcd (or ohci-hcd), the problem will disappear, too. > So is this a bios/mobo problem, Yes. > or can it be solved in kernel somehow? We could have usb-handoff by default. -- Vojtech Pavlik SuSE Labs, SuSE CR - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
