I notice this is called from a subsys_initcall(). We scan the PCI bus much earlier in arch/x86/kernel/early-quirks.c and it would be possible to identify presence of Thunderbolt host controllers in an early quirk (using the method of pci_is_thunderbolt_attached()) and, if found, enable their GPEs or all GPEs. Just as an aside in case your method doesn't work, I'm not affected by this issue being a Mac user... ;-) Thanks, Lukas -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
