intel dh55hc madness

[anibalin]

hey guys, im struggling with this one.

core i5 650, bios build #28 / Using chimera 1.7 & 10.7.2

The problem is that I get AICPM kp at boot.

This is the Scope PR for i5 processors:

    Scope (_PR)
   {
       Processor (CPU0, 0x01, 0x00000410, 0x06)
       {
       }
       Processor (CPU1, 0x02, 0x00000410, 0x06)
       {
       }
       Processor (CPU2, 0x03, 0x00000410, 0x06)
       {
       }
       Processor (CPU3, 0x04, 0x00000410, 0x06)
       {
       }
       Processor (CPU4, 0x05, 0x00000410, 0x06)
       {
       }
       Processor (CPU5, 0x06, 0x00000410, 0x06)
       {
       }
       Processor (CPU6, 0x07, 0x00000410, 0x06)
       {
       }
       Processor (CPU7, 0x08, 0x00000410, 0x06)
       {
       }
   }

 

If I use the dsdt file without scope pr on it I get at boot time:

ACPI CPUs not found: C-States not generated !!!

ACPI CPUs not found: P-States not generated !!!

But system loads up ok.

However, If I add scope pr to dsdt file I get:

SSDT with CPU C-States generated successfully

SSDT with CPU P-States generated successfully

but I get this KP afterwards:

"Should have 4 threads, but only found 5 for Die 0".

Have you tried with older BIOS versions?

I read about other Intel boards which only work (AICPUPM) using older BIOS (0144 for DP55WB)

for the sake of helping others:

I felt a little creative today and changed the scope from:

Scope (_PR)

{

Processor (CPU0, 0x01, 0x00000410, 0x06)

{

}

Processor (CPU1, 0x02, 0x00000410, 0x06)

{

}

Processor (CPU2, 0x03, 0x00000410, 0x06)

blah blah

to:

{

Scope (_PR)

{

Processor (CPU1, 0x01, 0x00000410, 0x06)

{

}

Processor (CPU2, 0x02, 0x00000410, 0x06)

{

}

Processor (CPU3, 0x03, 0x00000410, 0x06)

blah blah

The hint? was the die 0 at the kp. Made me wonder if it could be just that...and it was.

[anibalin]

thanks for your reply Cassio. Yes, that was the first thing I tried. I had a dp55wb and was aware of the bios build too. Thanks for the kind pointer though.

Warm regards.

Well done. Thanks for sharing.

Best regards.

Cassio any hint why I may be getting LPC device initialization failed C-state power? AppleLPC gets loaded though.

Maybe bad _CST in SSDT? Check the generated tables.

Some people use custom SSDT instead of Chameleon "generate P & C states"

That happens with me when I enable Use Kernel Cache. Try disabling it.

thanks guys. Ended up making some ssdts.

Hi,

I got DH55TC (Bios #48) which is similar to DH55HC - Core i3 530 SMBios- iMac 11,1 running mountain lion 10.8.0,

I am able to generate PStates using the following processor scope,

Scope (_PR)

{

Processor (CPU1, 0x01, 0x00000410, 0x06)

{

}

Processor (CPU2, 0x02, 0x00000410, 0x06)

{

}

Processor (CPU3, 0x03, 0x00000410, 0x06)

{

}

Processor (CPU4, 0x04, 0x00000410, 0x06)

{

}

Processor (CPU5, 0x05, 0x00000410, 0x06)

{

}

Processor (CPU6, 0x06, 0x00000410, 0x06)

{

}

Processor (CPU7, 0x07, 0x00000410, 0x06)

{

}

Processor (CPU8, 0x08, 0x00000410, 0x06)

{

}

}

I get PStates Generated but end with a Kernel Panic as shown in the picture. I cannot downgrade to BIOS #28 as my processor is not supported in that version.

Have you achieved native speed stepping ? Please share your DSDT.
