Yes - it shows a test case issue with the upcall and psample tests.

Adrian and I discussed the correct approach would be using a wait_for
instead of just sleeping, because it seems the dbg environment might be
too racy.  I think he is working on a follow up to submit after the
psample work gets merged - we were hoping not to hold that patch series
up with more potential conflicts or merge issues if that's okay.
