Title:
  cpu hot-remove fails with nvme device

Status in HWE Next:
  In Progress
Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Vivid:
  Fix Released

Bug description:
  Using cpu hotplug to disable (offline) a cpu:
  echo 0 > /sys/devices/system/cpu/cpu10/online
  does not return.

  Machine is usable, and cpu10 is marked as offline, but any test
  scripts hangs because the "echo 0" never returned.

  Doing bisect pointed to this commit id: a4aea5623d "NVMe: Convert to blk-mq"
  Indeed, the test machine in question has an NVMe card.
  Doing "rmmod nvme" and then disabling cpus works.
