Implication: One or more of the following symptoms may occur:
Intel
• 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 incomplete (i.e. the
• The maximum expected V
• 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, resulting in
• During Resume from S3: System may hang when attempting to initialize SATA Gen1 devices.
