  Current nvme driver in Ubuntu 16.04 kernel does not handle error recovery; we 
are missing some patches from the upstream nvme driver.

  We would like to ask Canonical to cherry pick the following patches for the 
16.04 kernel, if possible:
      * 9396dec916c0 ("nvme: use a work item to submit async event requests")
      * 79f2b358c9ba ("nvme: don't poll the CQ from the kthread")
      * 2d55cd5f511d ("nvme: replace the kthread with a per-device watchdog 
      * 9bf2b972afea ("NVMe: Fix reset/remove race")
      * c875a7093f04 ("nvme: Avoid reset work on watchdog timer function during 
error recovery")
      * a5229050b69c ("NVMe: Always use MSI/MSI-x interrupts")
