Just an additional data point, I ran this test (using Mike's script in a loop) on other architectures:
amd64 bare metal: 30 times 4.4.0, no failures amd64 virtual machine: 30 times, 4.4.0, no failures
s390 4GB RAM: 40 times on both 4.4.0-31 and 4.7.0, no failures s390 20GB RAM: 40 times on both 4.4.0-31 and 4.7.0, no failures.
I'm still running on arm64 and waiting on final results.
