Leopard boots, but KP's on second reboot

[nu1mlock]

Hello!

 

I've been using iPC to install Leopard 10.5.6 in order to install SL later on. The install works fine (sometimes) and I get into OSX to create my user account. It all works great.

 

However, my system always kernel panics on the second reboot, forcing me to do another install.

 

I don't have a camera to take a photo of it, but the backtrace says the following:

 

com.apple.driver.AppleACPIPlatform(1.0.3)@0x554ac000->0x554e2fff

dependency: com.apple.iokit.IOPCIFamily(3.3.0)@0x5544a000

dependency: com.apple.iokit.IOACPIFamily(1.2.0)@0x55465000

 

Just before the above, there is some mentioning about IntelPowerManagement (or something like that). I belive there was some timeout (?).

 

Any idea how to make OSX NOT to KP on second reboot?

 

Thanks!
