Ahem... what I meant is that it is not realistic for me to sacrifice
one of the CPUs just to hope to get more stability.

I intended the suggestion was "turn off SMP support if you have only
one CPU". Thinking about it, the kernel is already no-SMP on systems
with one CPU nowadays, right?

Anyway, the problem happened again one hour ago, so I just decided
to upgrade only the kernel to the one from F15 and hope for the best.
If it happens again, I will then upgrade Xorg and Mesa.
