Hmmm. IIRC ppc_4xx_eth_initialize() is only called once upon bootup for ethernet driver initialization. The function called each time before network action is ppc_4xx_eth_init(). > One fix might be to free( dev->priv ) at the end of ppc_4xx_eth_halt(). > I tried this today and noted no ill effects. So did it work for you?
