It is more likely that the problem is in one of the devices (above) using IRQ21. I assume that the touchpad is uhci_hcd:usb7? What does "lsusb" show on this machine? Of course I'd recommend trying to reproduce the issue after excluding "ndiswrapper" from the configuration. cheers, Len Brown, Intel Open Source Technology Center
