> I'd also like to know how or what we need to do in order to proceed and getting this fix for GA? I opened bug 1647887 separately for this (I'm working on this problem for a separate situation and I forgot about using this bug to track the patch, oops) and the kernel patch to fix this is in the process of being included into the xenial kernel, so it's just a matter of time to wait for the kernel update process, until a fixed kernel is released. ** This bug has been marked a duplicate of bug 1647887 NVMe driver accidentally reverted to use GSI instead of MSIX -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1639920 Title: NVMe detection failed during bootup Status in linux package in Ubuntu: Triaged Bug description: 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.
