Hi Mr Borril!

Yes, I remember distinctly on the same machine, it never appeared on 3.0
only when I updated it to stable branch. The said message appeared.

The file if_bge.c says something that if NIC is 5750 above it would
generate that message. (XXX broadcom-supplied linux driver; undocumented).
I wonder what that means.
