SYMPTOMS

On a computer that is running Windows Server 2008 or Windows Vista, you change the Serial Advanced Technology Attachment (SATA) mode of a disk device to use the Advanced Host Controller Interface (AHCI) specification in the BIOS setup stage. After the setting takes effect, the computer randomly stops responding for 60 seconds or longer.

Notes

This problem occurs more frequently under heavy disk I/O conditions.

Any application that performs I/O operations on SATA/AHCI devices may also stop responding. For example, Windows Explorer may stop responding when it performs I/O operations on SATA/AHCI devices.

CAUSE

This problem occurs because of a race condition between the interrupt handler in the AHCI driver (Msahci.sys) and the disk device. Therefore, the AHCI driver does not detect that some I/O requests are completed until the time-out handler collects these requests 60 seconds later. The race condition may occur because the driver does not follow the AHCI specifications to access related registers.

RESOLUTION

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both of these operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    VersionProductSR_LevelService branch
    6.0.600 0 . 20xxxWindows VistaRTMLDR
    6.0.600 1 . 22xxxWindows Vista and Windows Server 2008SP1LDR
    6.0.600 2 . 22xxxWindows Vista and Windows Server 2008SP2LDR
  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
