Hmmm, i just tested with Konstantin's patch on 2.6.25 and
2.6.26-rc3, and it seemed to work for me.

I set up a global hardware breakpoint at do_sync here.
Then i entered 'sync' command from a shell. The system dropped into KDB:
Instruction(Register) breakpoint #0 at 0xc017b6a4
0xc017b6a4 do_sync: push %ebx

You are testing a 2.4.21 kernel... I do not know if KDB support i386
in 2.4.21 at all.
Keith Owens did a tremendous job in making KDB backtrace working on
x86_64/i386 and fixed other bugs along the way, but his work did not
complete until 2.6.23. My brief effort of back porting the x86_64/i386
KDB support to sles10sp2 (2.6.16 based) and rhel5.2 (2.6.18 based)
did not work well. So, honestly, i recommand you move up to 2.6.23
or later.
Thanks,
