Does anyone have experience with how long the Management Engine's "Power Down Mitigation" timer is on Skylake? My Chell Chromebook with modified ME firmware reports this on bootup / S3 resume:
ME: FW Partition Table : BAD ME: Bringup Loader Failure : YES ME: Firmware Init Complete : YES ME: Manufacturing Mode : YES ME: Boot Options Present : YES ME: Update In Progress : YES ME: D3 Support : YES ME: D0i3 Support : YES ME: Low Power State Enabled : YES ME: Power Gated : YES ME: CPU Replaced : YES ME: CPU Replacement Valid : YES ME: Current Working State : Unknown (15) ME: Current Operation State : M0 without UMA but with error ME: Current Operation Mode : M0 without UMA ME: Error Code : Preboot ME: Progress Phase : <NULL> ME: Power Management Event : CM0PG->CM0 ME: Progress Phase State : Unknown phase: 0x0f state: 0xff ME: Power Down Mitigation : YES ME: PD Mitigation State : Issue Detected but not Recovered ME: Encryption Key Override : Workaround Applied ME: Encryption Key Check : FAIL ME: PCH Configuration Info : Changed ME: Firmware SKU : Unknown (0x7) It's been up for almost two hours without shutting down. The only drawback so far is that FSP takes quite a bit longer to complete. -- Trammell -- coreboot mailing list: coreboot@coreboot.org https://www.coreboot.org/mailman/listinfo/coreboot
