Subject: page allocation failure. order:2, mode:0x204020 with tg3 driver

Hi,

I have the same problem described here:
http://www.spinics.net/lists/netdev/msg295266.html
but with the tg3 driver. Anyone know if this can be or is fixed? I'm
using Debian 7 and kernel 3.16.7-ckt11-1~bpo70+1 from backports. I'm
using jumbo frames too, and haven't tried to disable it because the
server is in production environment.

Here it is the relevant log fragment:
