Thanks for the info. hmm, the section mapping in gdb looks wrong.. What is printed with these? crash> set debug 1 crash> mod -s xxx crash> gdb info address sysdump_panic_event crash> gdb info symbol sysdump_panic_event -- Crash-utility mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxxxxxx https://${domain_name}/admin/lists/devel.lists.crash-utility.osci.io/ Contribution Guidelines: https://github.com/crash-utility/crash/wiki
