Installed Kalyway 10.5.2 vanilla and as soon as enabling dual core in bios it fails to work, it works a bit and display is faded with a sign to shutdown computer.

Could you advise what kext is faulty? How to check dump for fault?

Sounds like you are having DSDT errors. Search around the forums, you'll find the thread.

I patched with DSDT and tried to boot with cpus=2 option and after some minutes it stopped working.

I used ApplIntelCPUPowerManagement but the same situation and besides temperature is 20 degreece higher.

Any chances to get stable 2 cores working?

Finally i did it! HP NX9420 working with 2 cores enabled!!!
This fix may also work for other NXxxxx series with centrino duo..

My cpu is T2500 2.00GHz
os:snow leopard 10.6.4

dsdt patch needed
just replace that value with 0x46:
0x46, Zero, Zero, Zero)
}
}

Method (PPC, 0, NotSerialized)
{
Return (C00A ())
}
}

Processor (_PR.CPU1, 0x02, 0x00001010, 0x06)
{
Method (PPC, 0, NotSerialized)
{
Return (C00A ())
}
}
_linenums:0'>Name (C000, 0xFD) Name (C001, Zero) Processor (_PR.CPU0, 0x01, 0x00001010, 0x06) { Name (C002, Zero) Method (CSTH, 0, NotSerialized) { If (LEqual (C002, Zero)) { Store (One, C002) Store (Zero, \_SB.C003.C004.C005) } Store (\_SB.C003.C004.C006.C007 (), Local0) Return (Local0) } Method (INI, 0, NotSerialized) { If (LAnd (And (\_SB.C008, 0x01000000), LEqual (C009 (), 0x04))) { \_SB.ISMI (0x46, Zero, Zero, Zero) } } Method (PPC, 0, NotSerialized) { Return (C00A ()) } } Processor (_PR.CPU1, 0x02, 0x00001010, 0x06) { Method (PPC, 0, NotSerialized) { Return (C00A ()) } }



also here this line added:\_SB.ISMI (0x46, Zero, Zero, Zero):
\_SB.ISMI (0x46, Zero, Zero, Zero)
} _linenums:0'>Method (_SB._INI, 0, NotSerialized) { \C009 () C01C () \_SB.ISMI (0x46, Zero, Zero, Zero) }

sometimes it hangs at the very begining, if you did a hard shotdown previously(pressing pwr button for 5 sec)
otherwise it boots and works fine!!!
