I can say that I ran 1000 trials of generic/299 on nojournal using a vanilla 4.1-rc6 kernel on a Pandaboard successfully with fio 2.2.6. No failures, and completed in ~61 hours for an average test duration of ~3.7 minutes, which agrees well with what I see when sampling the logged output for individual test times.
