Anyway, I think Eric is right, the bug may be in other place. I am wondering
if the attached patch could help? It seems in netpoll tx path, we miss the
chance of calling ->ndo_select_queue().

Please give it a try.

This fixes the NULL deref as well. I applied your patch over vanilla
3.6-rc5 (so without eric's patch) and I can load netconsole without it
crashing directly.

I will try to put a bit of load on the machine and see how it behaves,
if it solves the hung cpu tasks as well.

So far so good, the machine is still alive and well after 3 days with
netconsole enabled.

Great!

Thanks a lot for testing, Sylvain! I will post the patch tomorrow, as I 
need some sleep now. :)
