The test failure on dragonboard 410c comes from [1] to fix a possible deadlock related to the hotplug rework. It's been reverted in v4.12 by [2] because the cpu hotplug rework was not ready yet at that time. Since the hotplug rework has not been backported to v4.9.y, the splat cannot be reproduced and so [1] can be reverted or [2] applied on v4.9.y.
