There's a bug in usb_atm reference counting that might be the reason:
udsl_destroy_instance kfrees udsl_instance_data, while the latter is a
member of {speedtch,cxacru,...}_instance_data and not kmalloced

I'll go through the refcounting stuff and try to come up with a proper
fix tonight or tomorrow.
