Ok. Now I understand better. Maybe it's the same problem which I found in my first implementation: the AP was stuck, and the scheduler was sending all threads to the BSP.
Try to debug it using gdb, and checking the registers values in qemu monitor.

Believe me, I have tried a lot! I'm at a point where I could use some help. My old branch booted because the APs were in fact stuck as you described. But with this patchset we have APs servicing interrupts periodically and resting in idle loops.
This is very different to being stuck.

Please try it. It's likely to be a few lines of code away from being bootable but I can't seem to figure it out yet.
