I've been running an on-off test on a couple of Power8 systems and have
been getting a failure of detection on the NVMe drives on Ubuntu 16.04.1
only. I've ran the same test on RHEL 7.2 and have not encountered this
proble. Once the problem occurs the OS will stop to boot up and a
message appears:
Welcome to emergency mode! After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to try
again to boot into default mode.
Give root password for maintenance (or press Control-D to continue):
