I've seen at least two occurrences of a non-deterministic test failure
in qemu for x86_64 on hydra.  Both are essentially the same, except for
the random seed.  Here's the relevant log tail of the most recent one:

The excerpt above was from the first attempt of the following build:

  http://hydra.gnu.org/build/557468

After restarting the build, the second attempt succeeded.

I saved a full log from another similar failure on 10 June 2015, but I
neglected to save the other details.  Here's the relevant tail:
