Description

This issue was created by maloo for Bob Glossman <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/5a28029e-936f-11e7-ba84-5254006e85c2.

The sub-test test_53b failed with the following error:

test failed to respond and timed out

client mount hangs, eventually auto test times out and kills everything.
Stack traces like this can be seen in console logs & syslog of client1:
