i386 MP failure (yet another sequel)

[Vincent <10.50%free.fr@localhost>]

Hi to all,

well, I dug a bit farther and added "options MPDEBUG" to my kernel.
Of course, after the cpu1 failure, I dropped into DDB. I poked around, 
found nothing, so I entered "cont" to resume boot.

And... I got the CPU1 working allright (see dmesg).

I wonder if this is casused by a too short delay? What else can happen? 
If I just type "cont" undeer DDB, it works okay too. That's strange.

But if I remove the "options MPDEBUG", I fall back to the old behavior, 
CPU1 won't work.

Vincent
