Public bug reported:
After suspending my computer to standby and then waking it up again,
networking restarts unreliably: Sometimes it restarts fine, sometimes it
takes a few seconds to restart, and sometimes it takes more than a
minute (I didn't wait longer).
When the network wakeup is not finished, pings to my local router get a
timeout, and "sudo service networking restart" creates this output:
klee@gonzales:~$ ping router
PING router (192.168.100.254) 56(84) bytes of data.
