Method (DSSM, 0, NotSerialized)
{
If (LEqual (0x00, DSEN))
{
Store (CADL, PADL)
If (LEqual (OSTP, 0x03))
{
Notify (\_SB.PCI0, 0x00)
}
Else
{
Notify (\_SB.PCI0.GFX0, 0x00)
}
Sleep (0x03E8)
Notify (\_SB.PCI0.GFX0, 0x80)
}
If (LEqual (0x01, DSEN))
{
\_SB.PCI0.LPC0.PHSS (0x01)
Notify (\_SB.PCI0.GFX0, 0x81)
}
}
If DSEN == 0x01, video driver will get notification 0x81.
Method (_DOS, 1, NotSerialized)
{
Store (And (Arg0, 0x03), DSEN)
}
And DSEN is set by the _DOS method.
So first please try "echo 0 >/proc/acpi/video/GFX0/DOS" and see if there is
any difference.
If the system still hangs, please apply the debug patch in comment #9 and
reload the acpi video driver.
