I just tested experimental, same issue there withlinux-image-5.0.0-trunk-marvell (5.0.2-1~exp1).

After digging around I assume this problem is related to changes indrivers/net/ethernet/marvell/mvmdio.c in Version 4.12, which extendedthe number of possible clock sources, see [1].

Just a couple of days ago there was a "fix" posted in [2], which checksthe array introduced above, before accessing it.
