Problem with kdb kernel debugger patch against 2.2.19

Hello [email protected],

I patched my 2.2.19 kernel with the SGI kdb patch to have the ability of kernel debugging and especially debugging of the kernel modules I write.
I had to install libbfd and the kernel seems just to compile perfectly. Lateron I get the following error :

/usr/src/linux # make bzImage

[...]

make: *** [_dir_arch/i386/kernel] Error 2

What does
"/tmp/ccVx3zpC.s:1024: Fatal error: Symbol machine_check already defined." mean, how can I solve it to get my kernel with kdb ?

Note: I'm still using 2.2.19 because of module development to test kernel modules for 2.2.x.

Thanks in advance, Markus
