[Crash-utility] core file contents

I have two different core files generated from two different kernels. I noticed one contains all segments crash> sym -m dpm_kstat ffffffffa00c4000 MODULE START: my_kstat ... ffffffffa00c5290 (t) kstat_numrange_create ffffffffa00c55a0 (r) __func__.41073 ... ffffffffa00c5ddb (r) __kstrtab_kstat_numrange_iter_init ffffffffa00c5e60 (d) dprintflevel_kstat ... ffffffffa00c5f40 (d) __this_module ffffffffa00c61a0 (b) kstat_spinlock ... ffffffffa00c6e5e MODULE END: my_kstat while the other contains only text segments. Is there some define in the kernel config or in core file generation which causes this? crash> sym -m dpm_kstat ffffffffa00b9000 MODULE START: dpm_kstat ffffffffa00b9000 (t) kstat_cmd_gettbl ffffffffa00b9930 (t) kstat_exit ffffffffa00b9930 (t) cleanup_module ffffffffa00b9a20 (t) kstat_init ffffffffa00b9a20 (t) init_module ffffffffa00b9bb0 (t) kstat_unregister_provider ffffffffa00b9c90 (t) kstat_register_provider ffffffffa00b9dc0 (t) kstat_numrange_dprintf ffffffffa00b9fa0 (t) kstat_numrange_match ffffffffa00b9fe0 (t) kstat_numrange_iter_init ffffffffa00ba060 (t) kstat_numrange_destroy ffffffffa00ba0a0 (t) kstat_numrange_addentry ffffffffa00ba1e0 (t) kstat_numrange_create ffffffffa00bb5af MODULE END: dpm_kstat Thanks, Thomas
