Oh...sorry...looks like I am misinterpreting your e-mail :-)
ehm, AFAIK, stack frame pointer also determine the precision of stack dump, so
make sure you don't include -fomit-frame-pointer
CONFIG_KALLSYMS, ehm, for 2.6, right? well, I still use 2.4....that's why I
miss that option :-)

Yes, I agree. Bulls-eye stack dump is definitely useful to pin point
problem....and of course...you still need to fully understand the inner work.
it reminds me to Linus' wise word "Use the source,Luke" :-). Well, somehow I
need to pratice my Force's power to achieve Jedi senior warrior :-)))
