seems there is a race in drivers/net/usbnet.c in full RT mode. To be honest I haven't hardly checked this on the latest kernel and latest RT patch but just took a look at usbnet.c and latest RT patch and haven't observed any related changes.
thanks, i've applied your patch to my tree. Note that your patch is specific to the -RT kernel (both in terms of semantics and in term of API dependence), so it does not make any sense to apply it upstream.
David, please ignore it.
