This is the wrong mailing list for crash utility issues. Please send
your queries to crash-utility@redhat.com.
That being said, the "mod -s" command does the add-symbol-file command
behind the scenes. Your discrete "add-symbol-file" command is both
unnecessary and incorrect -- 0xffffffffa01d1240 is the address
of the nvme module's module data structure and not the starting
text address.

Hi,
I have been trying to debug a multi controller hang issue with crash.
It seems that crash works fine on stock ubuntu 14.04 running
3.13.0-39-generic. However when I recompile kernel and try to run
crash on it I get the following error:
crash> mod -s nvme ./nvme.ko
MODULE NAME SIZE OBJECT FILE
ffffffffa01d1240 nvme 58727 ./nvme.ko
crash> add-symbol-file ./nvme.ko 0xffffffffa01d1240
add symbol table from file "./nvme.ko" at
.text_addr = 0xffffffffa01d1240
Reading symbols from /root/mynvme.sriov/nvme.ko...DW_FORM_strp
pointing outside of .debug_str section [in module
/root/mynvme.sriov/nvme.ko]
gdb: gdb request failed: add-symbol-file ./nvme.ko 0xffffffffa01d1240
crash>
Any input on what I might have done wrong? Do I need to rebuild the
crash utility package along with the kernel?
Thanks,
Kallol
