(please cc netdev@vger.kernel.org on networking-related matters)

You died here:

static inline void napi_complete(struct napi_struct *n)
{
        BUG_ON(!test_bit(NAPI_STATE_SCHED, &n->state));

The NAPI changes have had a few problems and hopefully things have
been fixed up since then.  I'll try to get rc6-mm1 out this evening,
so please retest that?
