Can you please do some changes:

* reconfigure the console to be 80x50 or 80x60? That way we can see
the whole panic message
* can you please add some printfs() ? Just so we know the value of the
parameters being passed into that function?

It sounds like once the NIC goes into a "funny" state, it's corrupting
something (which may be the symptom; may be the problem) and free'ing
the TX/RX buffer ring contents is failing.
