I have this happen with my wireless interface (ipw2200) from time to
time, and I'm fairly sure it happened under FC6 too.
I have a theory, based entirely on conjecture and without a shred of
evidence. I think interfaces go through a period of being named __tmp*
during the driver load - I'm guessing after being detected, but before
the hardware initialisation has completed. The something happens that
prevents the final naming from completing. It's very bodgy looking.
A reboot is my usual fix (ugh, what a hack!). I have see a handy tool
somewhere for renaming interfaces; you could try that. It was called
"nameif" or something like that.
