kernel-4.16.7-300.fc28.x86_64 locks up it hard as soon as gdm starts.  Kernel
4.15.10 from Fedora 27 is OK.
Comment 1 H.J. Lu 2018-05-04 10:25:49 UTC 
My NUC is NUC6i5SYB.  Fedora 27 with kernel 4.16.7-200.fc27.x86_64 works fine.
Comment 2 H.J. Lu 2018-05-05 13:23:20 UTC 
I installed kernel 4.16.7-200.fc27.x86_64 on Fedora 28 and it works.
It looks like kernel-4.16.7-300.fc28.x86_64 is miscompiled by GCC 8.
Comment 3 H.J. Lu 2018-06-09 15:54:15 UTC 
This is caused by kernel config change from Fedora 27 to Fedora 28:
