here are some more information. 
I think there is a also a problem with memory after FEC crasched.

	Tim, Grant,
	
	just an info.
	
	Very often the Bestcomm-FEC crashed without any error logs if I initiate a transaction over FEC and save the file to disk (I rememeber I have read something like that). A restart of FEC don't work.
	But no I figured out, if I connect to the other ethernet port of our board (natsemi) the FEC will awake to life again, if I initiate a new transaction over natsemi. This seems a little oddly to me.
	


Hi guys,

We tried to get the SUSE guys to push the patch into openSUSE 11.1 release and the tests came back negative here too with regards to FEC support; for some odd reason, it does this;

There is some weird interaction here, but I can't imagine what it might be. Tim, did you ever see any ethernet problems like this?
