Title:
mem-on-off-test from memory-hotplug in ubuntu_kernel_selftests fails
with blocked task on B/F/G/H
Status in ubuntu-kernel-tests:
Triaged
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Bionic:
Incomplete
Bug description:
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: lp:1897764 and lp:1891003
