Robert,
I've just commented out the panic() in link_elf_obj.c and now i'm able to
create vlans again.
# svn diff link_elf_obj.c
Index: link_elf_obj.c

--- link_elf_obj.c (revision 195705)

vnet_data_copy(ef->progtab[pb].addr,
shdr[i].sh_size);

else
panic("link_elf_load_file:

"progbits type");
+#endif
} else
bzero(ef->progtab[pb].addr,
shdr[i].sh_size);
Now i'll get some sleep (too much coffee for a day...) or i'll not be able
to look at screen tomorrow =)
Thanks and regards,
Luiz
