This suggest that of the 7 instances of _PSW in the DSDT,
the one that is causing the failure is the one that
is checking the type of the OS (TPOS) for vista (0x40)
compatibility:
Device (PB6)
{
Name (_ADR, 0x00060000)
Name (MPRW, Package (0x02)
{
0x18,
0x05
})
Method (_PRW, 0, NotSerialized)
{
\_SB.QWMI.PHSR (0x11, 0x02)
Store (\_SB.PCI0.LPC0.OWNS, \_SB.QWMI.Q512)
If (LEqual (\_SB.PCI0.LPC0.WOLI, 0x00))
{
Store (0x00, Index (MPRW, 0x01))
}
Else
{
Store (0x05, Index (MPRW, 0x01))
}
Return (MPRW)
}
Method (_PSW, 1, NotSerialized)
{
Store (Arg0, \_SB.PCI0.SMB.WOLE)
If (LEqual (TPOS, 0x40))
{
Store (Arg0, \_SB.PCI0.SMB.WOLF)
}
}
The _PRW for this device says that he should be coming in
on GPE 0x18. Though in the working 2.6.25 kernel,
there are no interrupts recording on gpe-18, and in
the 2.6.30 this GPE is marked as disabled.
Just for grins...
The failing kernel has HPET support, the working kernel does not.
Please verify that you still see the failure with "hpet=disable"
