I'm not sure the exact reason, but Alexander patches the kernel a bit,
so it may come from there.
In general, though, the lfs kernel build is not set up to use
mismatched .config files. But it's easy to take a random .config and
have the kernel add on defaults and remove unused settings. Get the
old .config in place, then run
$ make oldconfig </dev/null
Tying /dev/null to stdin will just make the script accept the defaults
for all questions. Now you've got a working .config file and you can
tell jhalfs to use that one. Maybe jhalfs should do this by default,
but I don't recall exactly what it does there.

I don't remember the settings, but you can just tell jhalfs that
/usr/share/LFS-BOOK-6.2-XML is the local copy you want to use. Then it
won't try to do a checkout because it will consider that the checkout
is already done. It should be clear from the config menus which option
this is. I haven't run it in a while, though.
