The interfaces do get renamed early in the boot process.  We use
ifrename to force the e1000 interface to eth2.  The gianfar are on
eth0 and eth1.

Currently, there is no bonding configured at all.  While we do allow
bonding, there is currently no bonded interfaces.

I tried the up/down loop with the gianfar devices, and I do not get
the failure.  They are connected to the same network, and no problem.

I shutdown the gianfar adapters (eth0 and eth1) and re-ran the up/down
loop.  Still get the same panic.

That was the entire dmesg output.

Thanks,
