That isnt a supported/tested part of the PIII optimisations |
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
