1. PROBLEM: Unresolved symbols of _mmx_memcpy in modules on an Athlon XP
system
2. I've recently built a new server, and transplanted my linux installation
disks from an old server. The new server is an AMD Athlon XP 1800, the old
server was an AMD K6-II 500MHz.
The transplant went fine, however I haven't been able to successfully move
to an Athlon-optimised kernel. The kernel compile is fine, but when running
depmod -de after installing the modules, I'm faced with about 20 "unresolved
symbols". Each module is missing _mmx_memcpy.
I cannot get around it - I've tried everything, from the patch to
arch/i386/kernel/i386_ksyms.c to completely reconfiguring my kernel from a
brand new source tree. Nothing works.

8. I've done research and found that people have been experiencing this
problem from linux-2.4.0-test releases. Can someone please fix it?! Or point
me to a patch that works? :( The server's running on a chunky kernel
optimised for the old K6-II (i586).
Kind regards,
Alasdair McWilliam

urgs, for that long? surprising :)
Could you please try attached patch? Completely untested and just a guess.
Please report success/failure. Thanks
ciao, Marc

you must save your .config to another dir, then make mrproper,
then move your .config to your source tree, then make normally.
happens to me when i had an intel configured source tree, then
compile for amd.
-solca
The configuration file has never been setup for an Intel chip, it was
originally an AMD K6-II/500MHz. I've tried reconfiguring from a brand new
tarball for Athlon. What do I get?

Anyway as they are different sub-archs you must do a mrproper
first, then make normally.
