Stephen Kitt a70b95c017 agp: ensure GART has an address before enabling it ... Some BIOSs (eg. the AMI BIOS on the Asus P4P800 motherboard) don't initialise the GART address, and pcibios_assign_resources() can ignore it because it can be marked as a host bridge (see https://bugzilla.kernel.org/show_bug.cgi?id=24392#c5 for details). This was handled correctly up to 2.6.35, but the pci_enable_device() cleanup in 2.6.36 96576a9e1a ("agp: intel-agp: do not use PCI resources before pci_enable_device()") means that the kernel tries to enable the GART before assigning it an address; in such cases the GART overlaps with other device assignments and ends up being disabled. This patch fixes https://bugzilla.kernel.org/show_bug.cgi?id=24392 Note that I imagine efficeon-agp.c probably has the same problem, but I can't test that and I'd like to make sure this patch is suitable for -stable (since 2.6.36 and 2.6.37 are affected).
