After applying latest msk(4)/mii(4) in HEAD I was not able to reproduce the issue on Yukon Ultra controller. So would you try latest msk(4)/mii(4) in HEAD? Just copying the related files in HEAD(msk(4) files in /usr/src/sys/dev/msk directory and mii(4) files in /usr/src/sys/dev/mii directory) and rebuild your kernel.
