Curious.  Can you post what code you have at that line.  In my recent
checkout it looks like this:

490:    list_for_each_entry_safe(vif_state, tmp,
491:                             &accelerator->vif_states,
492:                             link) {
493:            /* Make sure there are no data path operations going on */
494:            netif_poll_disable(vif_state->np->netdev);
495:            netif_tx_lock_bh(vif_state->np->netdev);

Which doesn't seem to match the error you're getting.  No "do" for
example.

I'll try and reproduce it, but haven't seen this before, and the nearest
gcc version I have easily to hand is 3.4.3
