      Just curious, is this bare metal or a HV host?

      HV host

          Yes, but I only have 2 to choose from.

            What's the journal say the problem is? Usually it says what's preventing boot

              I started looking through that journal & gave up!
              I was doing this at 2AM on Xmas eve.
              I'll try again later today after biz hours.

              Is there a way to filter the journal output?

                  I usually look for red text or whatever it is.

                  If none, then you gotta scan it for with your eyes for errors or warnings.

                      Looked through the journal, there aren't any errors that would cause it to not boot.

                        "kk4ewt" on the fedora irc channel was helping me troubleshoot.

                        On the same hardware, I can "live usb" Fedora 27 WS LXDE w 4.14.8-300 but this same kernel with F27 Server will not boot!

                          I think I found the "issue"....
                          Under Manual Partitioning, for root (/) and boot (/boot), I'd been setting the file system to XFS.
                          I just did a test install using root as XFS & boot set to ext4.
                          I am now able to upgrade the kernel to 4.14.11-300
                          ** My other installs with SuperMicro hardware do not have this problem

                            That's weird, I've been using XFS for / and /boot all along... perhaps it's SuperMicro related.

                              This problem only exists with my 2 Lenovo servers.
                              All of my SuperMicro boxes are fine with XFS for / and /boot.

                                installed kernel: 4.13.9.300

                                Tried upgrading to 4.14.8-300...the system gets to the grub screen where I can see both available kernels...screen goes black...after waiting a few minutes, I ctrl-alt-del, reboot, choose 4.14..9-300

                                Anyone have a Lenovo server with upgraded kernel?

                                I've experienced the boot issue while using 4.14.11, I had to turn off Kernel Page Table Isolation (KPTI).
