mem-on-off-test from memory-hotplug fails with timeout and blocked task,
although visible is also invalid argument/unexpected success on Bionic
4.15.0-141.145
This is not a regression as it happened on 4.15.0-139.143 too, though
passed all tests on 4.15.0-140.144.
This same test is reported as failing, though with different output on:
