no symbol tabel in upgrade kernel

[hong zhang]

List,

When oops comes up, I can trace offending code line using

1. gdb *.ko
2. list *offending_address


to get an offending code line in commercial distribution.
But if I download newer kernel and do

1.make
2.make modules_install
3. make install

There is no symbol table compalin when I do "list *offending_address".

I could not figure out why.

Any help will be appreciated.
