  Lenovo Yoga 720 does not shutdown with wifi enabled

Status in linux package in Ubuntu:

Bug description:
  Whenever I try to shutdown or reboot the system while the internal
  wifi card is enabled, the systems hangs (system does not switch to
  command line mode, only possible to reboot using Syrq-Key+B, even
  Sysrq+O does not work). When I disable the wifi card using network
  manager before shutting down it works fine. The system runs in UEFI
