Problems with PXE + IPV6 + UEFI

[Jorge Cisneros]

Hi All

   I setup my pxe environment using the grub-mkdirnet for EFI and legacy, in both cases the ipv4 works very well, but when I try to use the ipv6 I got an error and sent me to the rescue shell

  You can see a screenshot here http://s22.postimg.org/av3zr0jz5/grubbug.png 

   Look like grub is trying to parse the ipv6 as ipv4 getting as result a very bad ip, 

   This is a bug? there is a workaround or I did something wrong?

Thanks

George
