State-Changed-Why: 
It seems there are two issues here.
 o Station address read by driver was ff:ff:ff:ff:ff:ff
 o PHY attach failure triggered panic

I have no idea for the first issue. It seems you have 88E8056 Yukon
Ultra controller which is known to have several stability issues
with msk(4). Due to lack of hardware I was not able to track down
the root cause of the issues.

However I can't reproduce the panic on my box when I patched the
driver to fail attaching a PHY. By chance are you using VIMAGE
enabled kernel? If yes, how about removing VIMAGE in your
configuration and test again?
