    Subject[10/18] x86: ASUS P4S800 reboot=bios quirk
    2.6.27-stable review patch.  If anyone has any objections, please let us know.

    From: Leann Ogasawara <>

    commit 4832ddda2ec4df96ea1eed334ae2dbd65fc1f541 upstream.

    Bug reporter noted their system with an ASUS P4S800 motherboard would
    hang when rebooting unless reboot=b was specified. Their dmidecode
    didn't contain descriptive System Information for Manufacturer or
    Product Name, so I used their Base Board Information to create a
    reboot quirk patch. The bug reporter confirmed this patch resolves
    the reboot hang.

    Handle 0x0001, DMI type 1, 25 bytes
    System Information
    Manufacturer: System Manufacturer
    Product Name: System Name
    Version: System Version
    Serial Number: SYS-1234567890
    UUID: E0BFCD8B-7948-D911-A953-E486B4EEB67F
    Wake-up Type: Power Switch

    Handle 0x0002, DMI type 2, 8 bytes
    Base Board Information
    Manufacturer: ASUSTeK Computer INC.
    Product Name: P4S800
    Version: REV 1.xx
    Serial Number: xxxxxxxxxxx


    ASUS P4S800 will hang when rebooting unless reboot=b is specified.
    Add a quirk to reboot through the bios.
