seems there is a race in drivers/net/usbnet.c in full RT mode. To be

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.
Is this action only take place on the same CPU, or is this also an SMP
problem? I would think if this is a race with full RT, that this may
also be a race with SMP, unless the race is guaranteed to always happen
on the same CPU. Then this is only a RT problem.
thanks, good point. looks like it could be SMP problem but probably
David is able to say it for sure as usb host code expert.
David?
