Re-tested on the ppc64le, this test has passed without any issue.

Re-tested on the azure instances, some of the can pass on the second run, some passed on the third.

So it's a bit difficult to reproduce this.

I can reliably reproduce the bug increasing the number of stress-ng instances while running the sysfs stressor (tested changing from 4 to 16).

I was able to reproduce the bug also with 4.13.0-37.42~16.04.1, so this is not a regression.

I suspected this issue is uncovered now due to recent changes on the stressor to make it more stressful.

Yes, I believe that is true, the stressors now try to exercise a wider set of sysfs files in a more efficient way, so I expect we're hitting pre existing issues.

4.13 is no longer supported in Artful, make sense to close this bug?

I'd close it, artful is EOL
