nv_do_nic_poll() is simply buggy and needs a fix.

synchronize_irq() can sleep.

Yes, but why did it start showing up now? None of this has changed as far as I can see?

Found one thing that changed - compiler from 6.2.0-9 to 6.2.1-5 and 
binutils too in debian unstable (explicitly upgraded to get fix to the 
binutils bug that broke 64-bit kernels).

Is it just timing and the transmit queue being busy? Perhaps due to the sheer size of messages? Meelis does seem to have a ton of debugging enabled..

Well, the dmesg is not too verbose but when I debugged some earlier 
problem, netconsole and many other debugging options were left on.
