I'd still like to see a dmesg log with no arguments (remove the "acpi=off pnpbios=off noapic nolapic" arguments). Your machine is new enough that we'll use PCI _CRS by default, and I'd like to make sure we're doing the right thing.
I assume that with no arguments, you still need the "skip transparent bridge sizing" change to boot.
I don't really like that change because in __pci_bus_size_bridges(), it's not obvious why sizing transparent bridges should be a problem. If growing transparent bridge windows makes us run out of space, let's put the smarts ("this bridge is transparent, we can take advantage of subtractive decode so we may not need to grow the positive decode windows") at the point where we grow, not at the point where we size. If we do have enough space, growing the positive decode windows is better because they're faster than subtractive decode.
