debian-amd64 2.6.8下编译内核的问题？

mythfish

有没人在debian-amd64平台下编译过2.6.12版的内核，我编译时是出错，先是processor.h里面的一个定义错误，后来修改过来，再编译出现：
arch/x86_64/kernel/entry.S: Assembler messages:
arch/x86_64/kernel/entry.S:81: Error: Macro with this name was already defined
arch/x86_64/kernel/entry.S:100: Error: Macro with this name was already defined
make[1]: *** [arch/x86_64/kernel/entry.o] 错误 1
make: *** [arch/x86_64/kernel] 错误 2

有那位大哥有出现过同样的问题吗？
是怎么回事？
