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:
