New SATA HD (CH7, Intel 945) - appleefiruntime.kext CRASH

[mitch_de]

Hi, i have ASUS G945 Board (SATA+PATA) , EFI V8.0 patched Intel Kernel 9.2

ID´s: 0x27df,8086 for CH7 PATA, 0x27c0, 8086 for CH7 SATA

 

(My UDMA-6 (SATA-II) is shown in IORegistryexplorer as UDMA 0x5 ?!

 

PROBLEM: Kernel Panic if boot from SATA with APPLEEFIRUNTIME.KEXT installed ?!

 

I can use my new SATA HD well (booting from IDE HD) , but not when i boot from it (kernel panic in appleefiruntime.kext).

 

If i REMOVE the appleefiruntime.kext i can boot from it without Kernel PANIC !!!

 

For what is that kext used ?

 

I had removed AppleViaATA, but didnt helped, (need to remove the appleefiruntime.kext)

 

What can that be:

Problem with AHCI.kext, SMSBIOS.KEXT, KERNEL ?

 

Booting from PATA is OK, even appleefiruntime.kext is not removed ?!

 

Thanks

 

 

HINT: AppleIntelPIIXATA kext fully working for all ICHx Mobo (All Sata Channels working)
