I do believe I'm getting something similar to this.
I don't have anything in logs that would suggest a fail, but after a
period of around 4-6 hours network inactivity, my system will freeze
once I start using the network device again (ie: checking for updates).

Also, don't know the importance of it, but this happens every 2-5 minutes, and
is the last thing that is logged before each crash. (This is a merge between
the daemon.log and kern.log)
