 After many tests and comparisons with other case, I found
 that the main difference was that in my case, the mptable
 show that the entry of the isa bus with pin# 0 has an int
 type of INT instread of ExtINT (in my case entry 0). Just
 to try, to put i386/isa/clock.c on the right track, I patch
 i386/i386/mp_machdep.c to force this entry (0) with
 int type ExtINT (at the end of function mptable_pass2).
 
 make buildkernel && make installkernel give me a running
 SMP kernel.
 
 Just to be sure my dream come true, I make buildwold and all
 was running smoothly  :-)
 
 I'm sure that this patch is just ad hoc for my case but maybe
 a smp guru may find a better way to correct the problem.
 
 Anyway, tt can be usefull to someone else:
