OK, got it.

Well, there seems to be a problem in the 1.3.0 driver (C:\Program 
Files\Atmel\AVR Tools\AVR32 
Studio\plugins\com.atmel.avr32.sf.uc3_1.7.0.201009140900\framework\1.7.0-AT32UC3\SERVICES\LWIP\lwip-port-1.3.0\AT32UC3A\netif\ethernetif.c)
 that has been fixed in the 1.3.2 driver:

ethernetif_input() should call "netif->input(p)" (which correctly obeys lwIP 
threading requirements) instead of calling "ethernet_intput(p)" (which violates 
threading requirements when called in multithreading configurations).

Also, you should pass "tcpip_input" as last parameter to "netif_add()" when 
using multithreading (NO_SYS defined to 0) and "ethernet_input" if NO_SYS is 
defined to 1.

Hope that helps.

No, there was no link on the page I found.
