SYMPTOMS
When you wake a Windows Vista-based computer from sleep (S3), the computer may stop responding (hang). When this problem occurs, the screen first becomes black. Then, you may eventually receive a Stop error message that resembles the following:


 * STOP: 0x0000009F

DRIVER_POWER_STATE_FAILURE

This problem may occur if the following conditions are true:
 * The computer is using a PCI-Express (PCI-E) graphics device.
 * The computer's firmware grants native support to the operating system for PCI-E features.
 * PCI-E Active State Power Management (ASPM) is enabled on the PCI-E graphics device.

This problem may occur intermittently.



CAUSE
This problem may occur if the PCI-E graphics device does not correctly exit the ASPM L1 power-state negotiation stage when a link-retrain sequence occurs on the PCI-E link.
