This time itīs gona to be funny for amdīs.
Last time there was time to get a solution until get 64 bit Userland working.
Now it wonīt work without it.

The problem isnīt the boot loader for sure.

@anv
Did you change something on the 32 Bit Kernel this time, or did you just edit the 64 bit kernel?

I added the code of the patch for both 32 and 64bit kernel.
I think Apple removed some routines which are required for AMD or changed some code which is giving the issues.
I diffed SL 10.6.8 versus 10.7.0 and there are a lot of differences (for example the commpage is a lot more empty).
It's like looking for a needle in a haystack :-|

the filesize difference between the 2 released xnu sources (10.7 and 10.7.1)

is huge

just tried the diff (without custom dyld and sse3emu etc.) on the latest source -> same result sadly

any way to debug this ?

I wish... somebody with a vanilla capable cpu should test it to see if it at least boots there...
I'm continuing looking for a solution (but it won't be easy...)

k and if it Boots there what would u need in logs to dig in

kernel.log ? or any other one ?

It didn't reboot on my 64bit Pentium 4 HT, but it crashed later in the boot. I can take a picture of the kp.

Yes but a P4 is also not Vanilla compatible. ;)

Unfortunetely the logs don't contain what I need.
I need to know which instruction causes the reset in case of the kernel in order to know what to do against it.

Good idea, it might help...

On a vanilla compatible cpu the kernel is working.
32 Bit + 64 Bit.
