SYMPTOMS

When you start a Windows Vista-based computer, you receive an error message that resembles the following:

*** STOP: 0x0000006F (parameter1, parameter2, parameter3, parameter4)
SESSION3_INITIALIZATION_FAILED

This problem occurs if the computer is using an onboard storage device or an external flash storage device that is managed by Windows ReadyBoost. This problem occurs only in certain hardware configurations.

Note Some computers may use an onboard integrated flash storage device that uses Windows ReadyBoost to improve system performance. On such a system, you may not be aware that Windows ReadyBoost is running, because the configuration and operation are automatic.

CAUSE
