[Crash-utility] How to get module symbols working ?

I am analyzing the kdump in latest crash utility 8.0.4++. I think I loaded the module symbols correctly : crash> mod MODULE NAME TEXT_BASE SIZE OBJECT FILE ffff80007a7e2040 npdereference ffff80007a7e0000 12288 (not loaded) [CONFIG_KALLSYMS] crash> crash> mod -s npdereference /home/naveen/.repos/src/arm64/linux/drivers/naveen/npdereference.ko MODULE NAME TEXT_BASE SIZE OBJECT FILE ffff80007a7e2040 npdereference ffff80007a7e0000 12288 /home/naveen/.repos/src/arm64/linux/drivers/naveen/npdereference.ko But still my backtrace doesn't say the correct symbol name : #12 [ffff800082c6ba60] _MODULE_INIT_TEXT_START_npdereference at ffff80007a7e602c [npdereference] The "sym" command also doesn't point me to the source file : crash> sym ffff80007a7e602c ffff80007a7e602c (m) _MODULE_INIT_TEXT_START_npdereference+44 [npdereference] crash> Is there a way to make this work correctly or at least make the "sym" command point to right source file. The kernel module here is called "npdereference.ko" and is in-tree (part of kernel source repo). Regards, Naveen
