For starters, I think we would need to see the messages. What has me 
concerned is whether you installed your kernel before you did the 
installworld. Version 5.2 has a different statfs, which needs the new 
kernel to run. An old world and a new kernel was fine but an old kernel 
and a new world was a show stopper. You had to use the fixit disk to 
recover your system. 

There are different options in the config file for 5.2 and you would 
need to start with a new GENERIC to create your MYKERNEL. Beyond that, 
I don't have any ideas at this point.
