Ouch, nice trick. But how do I actually pull it up? There's nothing that looks like allowing that in /sys:
root@amd:/sys/devices/pci0000:00/0000:00:1e.0/0000:02:02.0# ls broken_parity_status config irq power/ subsystem@ uevent bus@ device local_cpus resource subsystem_device vendor class enable modalias resource0 subsystem_vendor root@amd:/sys/devices/pci0000:00/0000:00:1e.0/0000:02:02.0#
I tried going to bus/drivers/ and unbind/rebind ipw2200 driver; that does not work. I tried echo 0 > enable; echo 1 > enable, but no trick, either.
