The most likely trigger is when there's not enough memory for the new device. Not too likely, especially because the device is compiled in and thus probes fairly early. When the bug bites, the driver dereferences a null pointer during cleanup from a failed probe. See bug 434802 for a proposed fix. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release.
