PET Alerts on SMBus
When using the ICH9 SMBus for Platform Event Trap (PET) alerts on a system with the
Intel® Management Engine (ME) enabled, the SMBus packet headers may be corrupted
if all of the following conditions are met:
ME firmware may stop functioning, which could cause a system hang.
No Fix. For steppings affected, see the Summary Table of Changes.
SMBus Host Controller May Hang
During heavy SMBus traffic utilization, the ICH9 SMBus host controller may attempt to
start a transaction while the bus is busy.
May cause the SMBus host controller to hang.
Contact your Intel field representative for details.
No Fix. For steppings affected, see the Summary Table of Changes.
SATA Gen1 Initialization/LPM Erratum
During SATA Initialization routines or while resuming from a Link Power Managed (LPM)
state, the ICH9 SATA link to Gen1 (1.5 Gb/s) devices may fail to be established.
One or more of the following symptoms may occur:
Contact your Intel field representative for details.
No Fix. For steppings affected, see the Summary Table of Changes.
• SMBus slave is the target of an external PET generating master on SMBus/SMLink
• The ME is in the middle of M0-M1 transitions
• SMBus slave receives back-to-back PET alerts of which some PET alerts are
• After boot:
• This issue has not been observed during boot as SMBus utilization tends to be light.
• During Boot or Resume from S4/S5: SATA Gen1 devices may not be detected,
• During Resume from S3: System may hang when attempting to initialize SATA
• During S0: If LPM is enabled and ALL SATA Gen1 devices within the system support
incomplete (i.e. the packet is truncated to less than 6 bytes)
resulting in “Operating System Not Found” error.
Gen1 devices.
LPM, slow SATA Gen1 performance may occur.
— SMBus host controller transaction may not complete.
— External master transaction in progress targeting ICH9 SMBus slave may get
— There is no impact to any other transaction that was in progress by an external
