It must be that skb->dev was changed to NULL inside of
__netif_receive_skb_core, otherwise we would have crashed much
earlier. Also, orig_dev is saved at the beginning. Possibly a device
is layered on top of the original device.

Exactly (skb->dev was changed to NULL ...). Do you think it makes sense to
put printks in various places in __netif_receive_skb_core to see after which
function call skb->dev turns into NULL?

No need anymore since Eric found the culprit in phonet_rcv.
Thanks for your help debugging this!
