(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?

And if you trigger this still it is absolutely critical that
you tell us what networking device driver you are using at
the time.
