Looks to me that LWIP does not respond to some ARP protocol requests of the host.
Can you give me a hint what happens if these debug messages appear? 2012-01-01 00:00:06 [W]gmac_low_level_input: DMA buffer 0x2045d878 received, size=64 [idx=1] 2012-01-01 00:00:06 [W]gmac_rx_populate_queue: new pbuf allocated: 0x2045de88 [idx=1] 2012-01-01 00:00:06 [W]ethernet_input: dest:ff:ff:ff:ff:ff:ff, src:98:e7:43:7a:2c:51, type:806 2012-01-01 00:00:06 [W]etharp_update_arp_entry: 0.0.0.0 - 98:e7:43:7a:2c:51 2012-01-01 00:00:06 [W]etharp_update_arp_entry: will not add non-unicast IP address to ARP cache 2012-01-01 00:00:06 [W]etharp_arp_input: incoming ARP request 2012-01-01 00:00:06 [W]etharp_arp_input: ARP request was not for us. 2012-01-01 00:00:07 [W]etharp_timer 2012-01-01 00:00:07 [W]gmac_low_level_input: DMA buffer 0x2045d268 received, size=64 [idx=2] 2012-01-01 00:00:07 [W]gmac_rx_populate_queue: new pbuf allocated: 0x2045d878 [idx=2] 2012-01-01 00:00:07 [W]ethernet_input: dest:ff:ff:ff:ff:ff:ff, src:98:e7:43:7a:2c:51, type:806 2012-01-01 00:00:07 [W]etharp_update_arp_entry: 192.168.0.9 - 98:e7:43:7a:2c:51 2012-01-01 00:00:07 [W]etharp_find_entry: found empty entry 0 2012-01-01 00:00:07 [W]etharp_find_entry: no empty entry found and not allowed to recycle 2012-01-01 00:00:07 [W]etharp_arp_input: incoming ARP request 2012-01-01 00:00:07 [W]etharp_arp_input: ARP request was not for us. I guess this is related to 153 545.813083 Dell_7a:2c:51 Broadcast ARP 42 Who has 192.168.0.100?

Or is this caused by a invalid/inappropriate network configuration?
