[U-Boot-Users] FW: PPC405EP ethernet problems

Good morning,

nevertheless I recommend to use the CONFIG_NET_MULTI option. You won't 
get rid of:

miiphy_register: non unique device name 'ppc_4xx_eth0'

without it. The message comes from reregistering the phy stuff over and 
over again.

Is it possible that there is any chace that you get an enetInt just 
after the first irq_install_handler? Can you put a printf at the 
beginning of the entInt?

But of course it could be an tooling issue. So hear what the expert said :-)
