However, I've noticed that there is some run-to-run variability in the results, even for a single kernel. Here are the tests that fail, either reliably, or worse, intermittently: reproducible failures: generic/042 generic/311 xfs/032 xfs/053 xfs/070 xfs/071 intermittent failures: generic/192 generic/247 generic/232 xfs/167 I don't have time to dig into things right now (and so I haven't included logs here since I'm not looking for help diagnosing the issues). What I'd like to know is if others also see this. Second, I was wondering if someone else has the time and motivation to look into this inconsistency. In case it's interesting, I run my tests on a Micron P320h PCIe SSD as the test device, and a regular sata disk as the scratch device. Cheers, Jeff
