Just let you know, Windows8.1 calls EFI on these boxes for reboot/shutdown. I'll be surprise if other windows version ignores RESET_REG_SUP to use ACPI reset registers. =========ACPI spec ============================== RESET_REG_SUP: If set, indicates the system supports system reset via the FADT RESET_REG as described in Section 4.8.3.6 ================================================= Thanks for checking that, please keep me posted. I'll re-submit the patch after you have an update. -Aubrey -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
