Public bug reported: The infra is currently testing linux-meta/4.4.0.41.43 which has some bug that it freezes the testbed (nothing actually runs any more and ssh hangs). The actual test timeout is being spotted correctly, but then it takes another two hours until it finally trips over some cleanup error/timeout -- this then gets counted as a tmpfail and the whole tests runs again:
