Hi Miles,
Looks like following processes failed to freeze while waiting
on the rtnl_mutex.
Either somebody is holding the rtnl_mutex for a really long time
Or the task holding rtnl_mutex is frozen.
I don't quite know about the former, but if it's the latter
then we definitely have a bug.
Thanks and Regards
gautham.
