I think this is a duplicate of the discussion we already had a couple of days ago, or did you hit another issue with live analysis on arm64 via crash? Please let me know. As I shared earlier, this issue is not reproducible with upstream linux kernel (5.8.0-rc3) and upstream crash-utility (./crash -v = crash 7.2.8++). See my logs below (on an arm64 machine): # ./crash -s /proc/kcore /root/git/linux/vmlinux WARNING: kernel relocated [0MB]: patching 102421 gdb minimal_symbol values crash> Please ensure that the following CONFIG options are enabled in your kernel config flags: CONFIG_KALLSYMS=y CONFIG_KALLSYMS_ALL=y Thanks, Bhupesh -- Crash-utility mailing list Crash-utility(a)redhat.com https://www.redhat.com/mailman/listinfo/crash-utility
