The old Apple ASIC had a bit somewhere to > control that, but I don't know about the NEC The NEC chip uses PME# for PCI wakeup, which pci_enable_wake(..., 0) is supposed to have disabled. If it's not disabling PME#, that's a bug in the PCI infrastructure on that platform. If some other signal is causing a wakeup, that's a different platform-specific issue. :) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
