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.
I wouldn't read too much into the data in there, it turns out the ME release that added this output detail (which we shipped in this device) also got it wrong so the data is not reliable.
