Indeed I have the
[    7.385851] Micrel KSZ9031 Gigabit PHY 2188000.ethernet-1:05: attached PHY 
driver [Micrel KSZ9031 Gigabit PHY] (mii_bus:phy_addr=2188000.ethernet-1:05, irq=-1)

first I rollback to a non crashing stable kernel.

As "bfe72442578b" gonna fix it I check with the next update and verify its works 
for me.

Thanks
Chris
