Subject: Re: Module mismatch
This is a Makefile bug. The include/linux/modules
files which have the symbol signatures don't get
updated properly when you switch between UP and
SMP configurations. I ran into a similar problem
last week.
The solution is to make a completely clean kernel
build by starting with make mrproper. This will
wipe out include/linux/modules and recreate them
to correspond to the UP or SMP versions. Then build
the modules you need.
