[Crash-utility] how to see local variables in frame

Hi, I don't see any option to see local variables in vmcore using crash utility. Tried gdb as well. Gdb is not able to dump stack. (gdb) bt #0 sysrq_handle_crash (key=99) at drivers/tty/sysrq.c:147 Backtrace stopped: Cannot access memory at address 0xffffb8c6c132fe40 (gdb) x 0xffffb8c6c132fe40 0xffffb8c6c132fe40: Cannot access memory at address 0xffffb8c6c132fe40 (gdb) info reg rsp rsp 0xffffb8c6c132fe38 0xffffb8c6c132fe38 (gdb) I have loaded symbols on specific .text, .data and .bss load addresses using following commands: gdb> add-symbol-file ~/crash3/vmlinux 0xffffffff97000000 -s .data 0xffffffff97c00000 -s .bss 0xffffffff97fa5000 I could decode .text and global .data symbols but not stack addresses and local variables. I have tried enabling CONFIG_FRAME_POINTER and also tried the latest version of gdb and crash as well but no help. Can someone please suggest and comment if this is indeed possible with gdb/crash to decode local variables from vmcore? Vimal Agrawal
