The patch that landed, https://review.whamcloud.com/37561/, puts sanityn tests 16a and 71a on the ALWAYS_EXCEPT list for PPC client testing. This ticket should remain open until those tests are fixed and the tests are taken off the list.

Also, PPC client testing fails this test 100% of the time; https://testing.whamcloud.com/test_sets/f25e7616-4a6e-11ea-b69a-52540065bddc.

I'm reopening this ticket because sanityn test 16a, as mentioned in the description, is still failing for ARM.
