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?
