I can build a 2.4.21-rc7 Athlon single processor kernel and modules without problem.

When I enable SMP, most (but not all) modules have unresolved symbols. This is basic stuff like prink and kmalloc. I've tried both with and without symbol versioning.

The build line was:
make clean && make dep && make bzImage && make modules && make modules_install

I'm building on RedHat 7.3.
#rpm -q gcc binutils modutils
gcc-2.96-113
binutils-2.11.93.0.2-11
modutils-2.4.18-3.7x

I'm not on the list. Please CC me.

w/o your .config a most impossible mission to fix this up.

Just a guess: Did you switch from UP to SMP with out doing "make mrproper"?

No, I didn't do "make mrproper". I'll try that.

It used to be that it wasn't needed and it liked to blow away .config (an extreme mis-feature if I ever saw one).

Thanks,

On 2.4 kernels, you must make mrproper when switching between SMP and UP.

You're missing a make install, I think ( at least this is what I do, perhaps something is redundant:

make clean
make dep
make bzImage
make install <<<<<<<<<<<<<<<<
make modules
make modules_install

Wthout the make install yu don't have nor the new kernel nor the System.map in /boot.

make install only works if you have something like "install_kernel.sh" script available in your system. not all systems have that. so it might just fail. and there is no problem by copying the System.map and bzImage by hand to the /boot directory

Right. I just copy by hand.

The kernel will boot just fine, but it can't load most of it's modules.
