For me, it was the recent lack of apathy - finally getting around to 
trying some combos for suspending my laptop, I noticed that having 
apic+smp in my kernel made me crash on boot.

Maybe it's some of the modules that have changed - the ones that caused 
the problems for me were:

snd_pcm
snd_ich
sound
vkbd

If those weren't loaded via loader.conf, I was fine.  Maybe the change 
is inside one of those.

As I've said before, I'm no coder, so take all that with a grain of salt 
- but hopefully it's helpful to someone.
