(SOLVED) Asus Z87-Pro + Haswell i5-4590 = instant reboot even using KernelPM

[bdv]

I am trying to install Mavericks (10.9.4 installer) on a brand new Asus Z87-Pro (V Edition) using Clover UEFI

 

Clover boots, load kexts (FakeSMC), patch kernel and reboots just after patching kernel.

 

 

Mobo: Asus Z87-Pro, latest bios (2103)

Proc: Core i5-4590

Graphic: GTX650 (with UEFI VBios GOP), runs OK on other UEFI Asus mobo

Ram: 2x8GB Crucial 1600 (run ok on other mobo)

Clover : r3193, UEFI mode, also tried with legacy mode : same instant reboot

 

Bios settings: as usual for Asus (I installed Z77, Z87M, Z87-WS, X79-WS, P8B-WS, P8C-WS, etc)

AHCI, No Memory Remap, no VT-d, IGPU deactivated, CSM disabled and "Other OS" (for UEFI boot).

The only new setting for this board is MSR 0x02 Lock : disabled or enabled. Set as disabled (default), also tried Enabled just in case : same instant reboot.

 

Clover settings: KernelPM + AsusCPUPM (tried also disabled)

 

With this release of Clover, I think that Haswell instant reboot bug should be cured by KernelPM ?

 

I also tried with a Yosemite Installer, even with myHack/Chameleon and legacy bios settings

 

Tried combination of npci=0x2000 or 0x3000, -xcpm (normally only for IvyBridge), samme reboot.

 

Any idea?

 

Solved by downgrading bios to 1802 release, it boots directly to the installer with the same settings.
