Kernel 4.15.10 from Fedora 27 is OK.
My NUC is NUC6i5SYB. Fedora 27 with kernel 4.16.7-200.fc27.x86_64 works fine.
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.
This is caused by kernel config change from Fedora 27 to Fedora 28: @@ -2307,7 +2304,7 @@ CONFIG_SATA_PMP=y # Controllers with non-SFF native interface # CONFIG_SATA_AHCI=y -CONFIG_SATA_MOBILE_LPM_POLICY=3 <<<<<<<<< Failed +CONFIG_SATA_MOBILE_LPM_POLICY=0 <<<<<<<<< Works CONFIG_SATA_AHCI_PLATFORM=m CONFIG_SATA_INIC162X=m CONFIG_SATA_ACARD_AHCI=m
