It is running.  Something  else needs to talk to it to trigger a crash.

But it doesn't crash with the first kernel that was without any fixes in instructions

@ydeng, are you still working on the opcode/ sse4.1emu?

Amazingly, your code seems to work, in part
I've integrated your emu into the last El Capitan Source and built a new kernel.
then I’ve noticed that the system was booted with "opemu ud2" error loop,

but at the end has reached the desktop.
then came the black screen followed by error loops. This is why i write partially.

 

I'm trying to build a new one and will report my new results.

Here's the latest code with debug prints.  I don't know how to make progress anymore.

I think I'll try first with  El Capitain and if it succeeds then with sierra.

my last kernel has not achieved the hoped result. I will make further attempts tomorrow.

After booting with the old El Capitan kernel, my desktop picture looks like this.(Pic.4)

If you don't know how to continue i tell to you to double check all the code and then try to make it more simple and then try to implement some functions to check that all the operations are done correctly, maybe something can go wrong and you will not see it, and also a network or serial debugger can be useful to read all the debug prints while they are hidden
