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:


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:
