Could you also attach lspci -v? It seems that the 0000:00:12.0 resource is nesting inside the 0000:00:14.2 resource, which is just not possible. Also, could you boot -rc5 (without a76117dfd687ec4be0a9a05214f3009cc5f73a42 reverted) with this patch applied? It may give us some idea of what's going wrong. diff --git a/drivers/pci/setup-res.c b/drivers/pci/setup-res.c index ec80b88..3f422db 100644 --- a/drivers/pci/setup-res.c +++ b/drivers/pci/setup-res.c @@ -105,6 +105,10 @@ int pci_claim_resource(struct pci_dev *dev, int resource) root = pci_find_parent_resource(dev, res); +if (root) + printk("Inserting resource %s %pR (BAR %d) inside resource %s %pR\n", res->name, res, resource, root->name, root); +else + printk("No parent found for resource %s %pR\n", res->name, res); err = -EINVAL; if (root != NULL) err = insert_resource(root, res); -- Matthew Wilcox Intel Open Source Technology Centre "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
