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.
3. Keywords: Kernel, Athlon, _mmx_memcpy, modules
4. Linux kernel version 2.4.20

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
