Fixes & Enhancements
Fixes:
* Rarely, the system may stop at POST (Power-On-Self-Test) when running reboot test in the BIOS boot mode.
* Several NVMe-related defects are resolved.
* It takes too long in the memory correctable Error-Correcting Code (ECC) logging System Management Interrupt (SMI), which impacts the Omni-Path Architecture Host Fabric Interface (OPA HFI) network performance. Fixed it by removing the redundant data logged to Serial Presence Detection (SPD) to reduce the SMI time from hundreds to several milliseconds.
* Resolved an Intel Management Engine related issue that caused the BIOS version update to fail (fails only when the server is kept turned on continuously for 24 days since the previous AC power cycle). See the Important notes section in this Release Notes.
Enhancements:
* Updated the Intel Trusted Execution Technology (Intel TXT) BIOS Authenticated Code Module (ACM) to version 1.3.4.
* Updated the Intel Processor and Memory Reference Code to PLR3.1.
* To address CVE-2017-5715 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2017-5715).
- Updated the Intel Xeon Processor Scalable Family Processor Microcode to version 0x43.
- CVE-2017-5753 and CVE-2017-5754 are addressed by Operating System & Hypervisor updates.
