tg3 crashes in scatter gather mode

[raz ben jehuda <razb@xxxxxxxxxxx>]

hello. 
I have written a fast udp stack that implements a real scatter gather
over user space pages. When i use it over an Intel e1000 card every
thing works fine.  doing the same thing over the tg3 crashes the system
somewhere in tg3_poll area. 
Anyone ?
