> Did you specify a led-mode as well, or was the Operation Mode Strap Override (OMSO) write the first access after the soft reset?
No led-mode was specified so OMSO was the first write.

I spend around 2 weeks hunting down the bug.
During which I tried many things in both the Freescale FEC MAC driver and the Micrel PHY driver.
Changing the init and the probe flow as well as adding a lot of extra debug traces.

Yes, pin 16 is floating.

> Would you able to test my series on your setup, and possibly a couple of diagnostic patches on top?
Sure, I can try later this week.
