Hi, I needed the attached patch to compile 2.4.20-rc1-ac3 on Uniprocessor. Alan, you seem to have too many multiprocessor boxes these days... :-) It might be possible that the same patch is needed in ./arch/ppc64/kernel/ppc_ksyms.c ./arch/mips/sibyte/sb1250/bcm1250_tbprof.c ./arch/ppc/kernel/ppc_ksyms.c ./arch/ia64/kernel/ia64_ksyms.c ./arch/parisc/kernel/parisc_ksyms.c But as I own none of these architectures, I can't be too sure.
