Description zero98 2000-05-15 09:31:24 UTC 
I have 550 Coopermine Processor. During rebuilding the kernel Red Hat 6.2
ver. 2.2.14 (included in distr) I have turned on two x86 optimization
options in CPU section of the build script (MMX/MMX2 support). I turned on
kmod too. During booting the system any modules started. Error reported:
unresolved symbol best_*( three optimised functions such as best_mem_copy
() etc. ) Then I have searched for this functions in kernel sources. They
declared as external in x86 optimization section. No one declaration for
those functions more. Then I have turned off x86 optimization options and
all began to work well.
   May be I make any mistake?

                       Best regards,
                                                Vadim Ivaninuk
