Comment 10 for bug 1308574

Additional data: This test succeeded on a Lenovo IdeaPad U530 (my personal laptop), on an OCP Windmill server, and under VirtualBox. This supports Colin's assertion that the problem is with the firmware on the computers that are failing (an Intel Decathlete, a Lenovo E530 laptop, and whatever IBM model Jeff is testing). OTOH:

1) A 50% success rate with this test is disturbing. That's not to say that the test is wrong to fail in such cases, but it's something that needs to be addressed.
2) It would be preferable for the test to fail without hanging.
