Ok, first freeze!
With the linux-image-2.6.18-6-686, what's the next step?
Nothing at all in the /var/log/messages.

I'll test now the "2.6.24.2-by-myckeul"[1] kernel.

It's a production server so I should found a solution for this bug or I 
return to the last solution, the downgrade of libc6.

Thanks,
