This is the record of GNU/Hurd boot crash (with my SMP GNU Mach core)

Feels an MMU problem in the Hurd servers start.

This is the record of GNU/Hurd boot crash with SMP

Feels that It crash when Hurd starts

It compiles!! :-)

I've just got to finish the GNU Mach compilation, patched to add SMP support.

You can see the code here: https://github.com/AlmuHS/GNUMach_SMP/tree/smp

I tried to boot Hurd using the new Mach image, but It crash.

Now I will need to debug my code.

In the compile log appears many interesting warning.

I have commented this lines at moment.

Finally, I got the equivalent call to cpu_desc_init64(cpu_datap(slot_num));

Also, I've replaced many others variables in the code.

The current code is here: https://github.com/AlmuHS/GNUMach_SMP/blob/smp/i386/i386/intel_startCPU.c

Now I'm searching the equivalency to this:

- IdlePTD in this line:

    DBG("IdlePTD(%p): 0x%x\n", &IdlePTD, (int) (uintptr_t)IdlePTD);

- the next variables and struct

   start_info.starter_cpu  = cpu_number();
   start_info.target_cpu   = slot_num;
   start_info.target_lapic = lapic;
   tsc_entry_barrier = 2;
   tsc_exit_barrier = 2;

hmmm.  This is a little out of my league, but I appreciate you for trying!
