Maybe the network drivers are few enough that it will get fixed, or
maybe the WARN_ON_ONCE() will just be removed and the rule not

I personally suspect the latter, since it seems to happen with just
about _any_ random network driver, including the common and
well-maintained ones (ie the Gods only help us for the truly
odd/random cases)

Yes, we'll see how this plays out.

Ian Schram just posted a patch for the NULL pointer derfer in
wireless Ingo reported, so we'll see if that bug will be fixed
now as well.

In the meantime: Is there perhaps something obviously wrong with drivers/ieee1394/eth1394.c's netdevice initialization? We do it in ether1394_add_host(), and shortly thereafter the crashing ether1394_host_reset() is called. So we have essentially

(add host)
dev = alloc_netdev(...);
initialize various members in dev...

(host reset)
discard some stale 1394 stuff if there were some...
netif_wake_queue(dev); <-- crashes in __netif_schedule(dev);
