unrelated to the issue in this bug report,
but of historical, or perhaps academic, significance...
the DSDT for this HP zx5000 laptop
implements the optional ACPI 2.0 _GTS (Going to Sleep) method:
Method (_GTS, 1, NotSerialized)
{
Store (0x01, \_SB.PCI0.LPC0.PWSC)
Store (0x00, \_SB.PCI0.LPC0.EC0.THEN)
Store (0x00, \_SB.PCI0.LPC0.EC0.DUTY)
If (LEqual (Arg0, 0x03))
{
Store (0x01, \_SB.PCI0.P2P.USB0.USS0)
Store (0x01, \_SB.PCI0.P2P.USB1.USS1)
Store (0x01, \_SB.PCI0.P2P.USB2.USS2)
}
}
...which appears to tickle some ATI chipset registers
on entry to suspend.
Curiously, the DSDT does not implement a matching _BFS method.
This is the 1st implementation of _GTS I've seen.
