Is vmcore.0 also new (i.e. produced with the new kernel)?
Does 'list ...' command still produces no useful output?
P.S. Also, hmm, I think that you shouldn't run kgdb on kernel.debug, just to
avoid any confusion... I think that you should run something like kgdb
/boot/${your installed kernel}/kernel /var/crash/vmcore.0; the debug symbols are
automatically picked up from *.symbols files in the kernel directory.
