On your failing I686
Note I show you the file names as on my x86_64 F16 

I suggest you look at /boot and the sizes of the *.img files for the
kernels. If the initramfs-3.3.2-1.fc16.x86_64.img is smaller than the 
initramfs-3.3.1-5.fc16.x86_64.img it kernel 3.3.2-1 didn't install
properly. 

I had this a kernel upgrade earlier and fixed it with by reinstalling 
the kernel it get it to create a proper initramfs file

yum reinstall kernel-3.3.2-1.fc16.i686
