Looks to be some kind of anomaly that's not related to these patches. I wasn't able to reproduce it again. I ran the last 16 tests (test 19 - 34) again, and they all passed. I may investigate that later, as running without DYNAMIC_FTRACE slows the system down enough to do strange things all over. I'll send out the pull request then. Thanks! -- Steve
