Hi!

Order 4 allocation... probably doable during boot, but not really
suitable during resume.
I'm not sure how repeatable it is, but it definitely happened more
than once.
/*
* real ring DMA buffer
* each ring/block may need up to 8 bytes for alignment, hence the
* additional bytes tacked onto the end.
*/
ring_header->size = size =
sizeof(struct atl1c_tpd_desc) * tpd_ring->count * 2 +
sizeof(struct atl1c_rx_free_desc) * rx_desc_count +
sizeof(struct atl1c_recv_ret_status) * rx_desc_count +
8 * 4;
ring_header->desc = pci_alloc_consistent(pdev, ring_header->size,
&ring_header->dma);
if (unlikely(!ring_header->desc)) {
dev_err(&pdev->dev, "pci_alloc_consistend failed\n");
goto err_nomem;
}
(Note the typo in dev_err... at least it is easy to grep).
Ok, so what went on is easy.. any ideas how to fix it?
