Hmmm... e1000 calls skb_trim() on both jumbo and non-jumbo ring buffers which get recycled.
At least for the Jumbo case, that's illegal as you cannot call skb_trim() on an SKB with paged data.
But this assertion is triggering for the non-jumbo ring where only linear packets should be present as far as I can tell.
Some Intel folks need to take a look, CC:'d, and people need to CC: their networking bug reports to netdev@vger.kernel.org so that the proper folks see it.
Thanks.
