SYMPTOMS

When you have a Trusted Platform Module (TPM) device running on a Windows Server 2008-based computer or on a Windows Vista-based computer, one of the following events may be logged in the Application log.

Message 1


Event ID: 10
Event Source: TPM
Event Type: Error
Event Description: A buffer underflow was detected

Message 2


Event ID: 11
Event Source: TPM
Even Type: Error
Event Description: A buffer overflow was detected
The TPM driver may log these errors when the TPM status register has the bit set to indicate an overrun or an underrun during communication between the driver and the TPM device. Generally, this error indicates a platform problem.

These events are logged when the TPM device cannot be accessed successfully because of hardware issues or because of firmware issues.

CAUSE

This issue occurs when the system BIOS is incompatible with the TPM device and must be updated.

WORKAROUND

To work around this issue, update your computer to the latest version of the system BIOS. If updating the system BIOS does not work, contact your computer manufacturer.
