Hi Stefan,
Yes CFG_RX_ETH_BUFFER is defined to 32.
I tried to define INFO_4XX_ENET in 4xx_enet.c and got the following output when the problem occurs.
=> run setup Trying ppc_4xx_eth0 About preceeding transfer (eth0): - Sent packet number 10626 - Received packet number 10632 - Handled packet number 10632 ENET Speed is 100 Mbps - FULL duplex connection BOOTP broadcast 1 DHCPHandler: got packet: (src=67, dst=68, len=300) state: 3 Filtering pkt = 0 DHCPHandler: got DHCP packet: (src=67, dst=68, len=300) state: 3 DHCP: state=SELECTING bp_file: "/tftpboot/kernel.img" TRANSITIONING TO REQUESTING STATE Bootfile: /tftpboot/kernel.img DhcpSendRequestPkt: Sending DHCPREQUEST Transmitting DHCPREQUEST packet: len = 343 DHCPHandler: got packet: (src=67, dst=68, len=300) state: 4 Filtering pkt = 0 DHCPHandler: got DHCP packet: (src=67, dst=68, len=300) state: 4 DHCP State: REQUESTING Bootfile: /tftpboot/kernel.img DHCP client bound to address 172.18.22.66 Using ppc_4xx_eth0 device TFTP from server 172.18.22.110; our IP address is 172.18.22.66 Filename '/tftpboot/kernel.img'.

We had problem with MAL error in Linux to untill we got a backport of the latest driver to our kernel. After that there is no problem in Linux.

Hi Andre,

CONFIG_NET_MULTI wasn't enabled. When I enable it the "miiphy_register: non unique device name 'ppc_4xx_eth0'" is exchanged with "Trying ppc_4xx_eth0", but it doesn't solve the main problem.
OK. One other idea: Do you have CFG_RX_ETH_BUFFER defined in your config file? If yes, what is the value? Try increasing it. I would suggest to use at least 16 rx buffers.
