20fcf9b = addition of RTC_S4 (bit 7). The patch i sent to add bit 15 does not touch that: - /* WBINVD + PROC_C1 + SLP_BUTTON + RTC_S4 */ - fadt->flags = cpu_to_le32((1 << 0) | (1 << 2) | (1 << 5) | (1 << 7)); + /* WBINVD + PROC_C1 + SLP_BUTTON + RTC_S4 + USE_PLATFORM_CLOCK */ + fadt->flags = cpu_to_le32((1 << 0) | (1 << 2) | (1 << 5) | (1 << 7) | + (1 << 15)); > They are both still valid.
