I just got a chance to test the 4.16.0-0.rc2 kernel using the 20180220 Xfce Rawhide Spin.  It fails to boot due to a kernel paging request.  Here are the snippets:

Hi Peter,

I just got a chance to update my Odroid Xu4 with the latest updates for
F27.
All was working fine with the exceptions for the Exynos 5 USB-3 issues
prior
to this upgrade.  After the upgrade and a reboot, my system no longer
boots
into graphics mode.  It seems to be failing somewhere along the line with
udev, but I am not certain of this.  The system will eventually boot into
non-graphics mode, which can be seen when connecting the serial port and
watching the boot messages.

As I mentioned in previous posts, the Rawhide Spins all seem to have this
issue too.  In fact, they have had the problem for a long time now.  On
the
positive side, both this release of F27 updates and the Rawhide spins do
seem to have the USB-3 issues fixed.
Can you try the 4.16rc2 kernel [1] and see if that has the same
issues. The 4.16 kernel might help as there was a bunch of stuff that
changed in the exynos drm driver.

https://koji.fedoraproject.org/koji/buildinfo?buildID=1046448
Looking at the builds in this URL I see "rawhide" listed as one of the
"Tasks".  Doe this mean the current rawhide build are already including the
kernel-4.16.0-0.rc2 kernel?
Yes, and the just branched F-28 will as well. So you can do an upgrade
to F-28 and get it there too

Attached, is a MS Word formatted file of my boot log.  Hope this helps.
Please don't do that, word processing docs are really not the way to
handle this in open source just fpaste it or something. If it's booted
just do "dmesg | fpaste" and provide the URL.

Regards,
Stewart

Hi All,

Just a heads up that the 4.15 kernel is headed to stable releases.

I did a bunch of testing over the weekend and fixed up a bunch of
issues, added some minor enhancements across a number of platforms.
There is a kernel-4.15.2-301.fc27 build [1] which had all those fixes
for people to test, I expect a 4.15.3 kernel going to updates-testing
later today or tomorrow.

A few notes for the fixes I added:
* fixed cpufreq/thermal on i.MX6 (thanks kwizart for upstream fix)
* Crypto/rng engine on some AllWinner devices now loads/works
(A10/A143/A20 at least, I suspect more will come with later kernels)
* Exynos 5 USB-3 issue should now be fixed once and for all (I hope)
* A bunch of improvements for monitor detection on the Raspberry Pi
* Ethernet driver more stable on AllWInner A64/H5 platforms (like
Pine64)
* Numerous other upstream fixes improvements that headed upstream
* 4.15.3 (not in the build above) will include aarch64 fixes for
Spectre/Meltdown.

So please test and feel free to reply to this thread with any new
issues you see with the 4.15 series, or any positive results.
