Thanks. This is a little odd -- I don't see why pskb_expand_head(skb, 0, 0) or pskb_expand_head(skb, 0, 18) would try to do an order 1 allocation when skb->len is 404 or 1728. It looks like something is forcing larger alignments than should be necessary, but I have no idea what. (for netdev: http://mid.gmane.org/49F8C03D.6040909@xxxxxxxxxxxx has more information) johannes
