SYMPTOMS

A Windows Vista-based computer that uses a Mobile Intel 945GM Express Chipset may occasionally not wake from sleep. This problem may occur about one time for every ten times that you try to resume the computer from sleep.

CAUSE

This problem occurs because of a race condition in the ATAportDeviceBusy function. The ATA miniport driver uses the ATAportDeviceBusy function to pause the device queues of the ATAport driver. When the race condition occurs, the queue can remain paused. This behavior causes the computer to stop responding.

This problem occurs if the computer is using the Microsoft Advanced Host Controller Interface (AHCI) chipset driver. The problem does not occur if the computer is using the Intel AHCI chipset driver.
