This will be a genuine bug. Not sure if its in the test case or code
yet....

This feels unrelated to the series, so possibly a non-deterministic
failure

I'm sure I've seen this non-deterministic failure before, unrelated to
this series.

Looking at the test source code, it has a 60 second wait for the
emulator to print expected data on the serial port. My guess
would be that when running with a highly parallel make check
we're sometimes exceeding that 60 seconds. I don't see a
reason why my series would have affected this in a way that
only failed with sparc64 qtest, and none others.

Sounds plausible. Feel free to resubmit the pullreq with the
actual bug fixed, for another spin of the intermittent-failure
roulette wheel :-)
