If you don't have any networked filesystems mounted, then I would be very 
surprised if changing the version of NFS built into your kernel would have 
any effect here.

At this point, I think the most useful information would be the kernel 
messages from shutdown time, printed on the console.  Do you have a serial 
console (makes this easy)? Otherwise, you may have to take a picture or 
video of the machine as it shuts down.
