Sorry for late reply.
I just returned from lunar New Year holiday.

These messages are printed from vr_stop() which is called
to stop the operation of the NIC. By any chance do you perodically
stop and restart the interface?

This message comes from vr_reset() which is always executed first
in vr_init_locked(). Don't know why soft reset does not work under
certain conditions. Datasheet for Rhine III(VT6105M, VT6105LOM)
says nothing about it. I guess you can ignore it unless this
message and above messages are continuously printed on your
console.
