Is there any problem with frequency?
No, I don't think that will cause you any problems. >From the interrupt count it doesn't look like you are getting any TX interrupts from the FEC. This will cause the NETDEV WATCHDOG to eventually timeout and you get the kernel trace you see. You are getting "other" interrupts from the FEC - I think you should add some trace and see what those are. Maybe they will give some clues.
