I was kind of stretching on that one. It was the only sched option you 
were missing that I had and it stood out.

I think it is important to cp GENERIC to your kernel config for each 
major update. Then, start adding "#" in column 1 to comment out 
features. It may seem like work but it saves more time trying to figure 
out why something is broken. 

My systems are pretty simple when it comes to the configuration and I 
can take a GENERIC and convert it into a new config file in probably 
less than 5-10 minutes. If you keep a copy of the old one around, you 
can run diff on your old and new config and see what is different.

When you start with a copy of GENERIC and delete features, your kernel 
config file is much more self documenting. Saving a few 100 bytes is 
not as important as keeping the structure of your config file so that 
people can key in very quickly on what you changed. This is especially 
true when you want free support :).

I am retired but got talked into helping resurect an old project for a 
couple of weeks for an old friend. That dropped 8 hours a day from the 
time I had available to figure out FreeBSD errors. I simply didn't have 
the time to take a 5.2 GENERIC and see what you had chosen to use.
