Comment 36 for bug 1736390

I'm swapping the bug back in and working on the bisect again. For some reason, all of the prior kernels that worked, are now freezing on the test while "Stopping Links":

*** Configuring hosts
h1 h2 h3 h4 h5 h6 h7 h8 h9 h10 h11 h12 h13 h14
*** Starting controller
c1
*** Starting 2 switches
s1 s2 ...
INFO:root:Running TCP performance test
*** Iperf: testing TCP bandwidth between h1 and h14
*** Results: ['20.9 Gbits/sec', '20.9 Gbits/sec']
INFO:root:Stopping network
*** Stopping 1 controllers
c1
*** Stopping 15 links
............

Has anyone else seen this?
