Operating Systems.Additionally, when used in conjunction with HP Smart Update Manager.
This Intel processor vulnerability is NOT unique to HP ProLiant servers. A customer can downgrade the System ROM by creating a new flash component with the older System ROM revision as indicated in Advisory C02838375 available at the following link: Firmware Dependencies: None Problems Fixed: Resolved a very rare issue where the system may either hang during system boot or boot with configuration options set incorrectly when non-volatile storage becomes corrupt. This is normally seen as the system hanging during system boot without anything displayed to video. Once the system gets into this state, the maintenance jumper can be utilized to recover operation of the system and restore configuration defaults. This revision of the System ROM will restore configuration defaults when non-volatile storage becomes corrupt. Proliant Ml350 G6 Upgrade Process RequiresNote: As enhancing the flash upgrade process requires modifications to both the System ROM and the flash update utility, the System ROM revision cannot be downgraded with the flash components available on the HP Support site after updating to this revision of the System ROM. This issue affects platforms utilizing Intel Xeon 5100-series, Intel Xeon 5200-series, Intel Xeon 5300-series, and Intel Xeon 5400-series processors. This issue is not unique to HP ProLiant servers and could impact any system using affected processors. This revision of the System ROM contains an updated version of Intels microcode for affected processors that addresses this issue. Due to the potential severity of the issue addressed in this revision of the System ROM, this System ROM upgrade is considered a critical fix. HP strongly recommends immediate update to firmware revisions with required critical fixes. Note: This processor issue has resulted in the following error being logged to the Integrated Management Log on servers configured with the HP ProLiant Health Management Agents when configured in a Microsoft Virtual Server environment with large numbers of Virtual Machines (VM) simultaneously subjected to a heavy IO workload (and may occur in other operating system environments): An Unrecoverable System Error has occurred (Error code 0x0000002D, 0x00000000). If the HP Health agents are installed when this condition occurs, the Integrated Management Log (IML) would contain at least one An Uncorrectable System Error has occurred (Error Code 0x0000002D, 0x00000000) entry. The failure condition is a result of a misalignment between the addressability range of the memory controller and this processor series and requires a unique type of software interaction. If the issue is not being seen, it is unlikely it will be observed unless a new driver, application, or OS is loaded. There is no performance impact associated with this fix and this issue does not affect Intel 5000-series processors. This System ROM update is needed to take full advantage of the power savings of this feature. Update to the latest revision of the Broadcom PXE option ROM (2.1 v4.6.8) for the embedded NIC.
