Introduction
Often in dmesg messages you have function names,for instance:
[ 71.030609] msm_adsp_disable() 'AUDPREPROCTASK'
In order to get the line number and source file path do:
# grep msm_adsp_disable System.map c029ff0c t msm_adsp_disable_locked c029ff68 T msm_adsp_disable c047fe98 r __ksymtab_msm_adsp_disable c049030e r __kstrtab_msm_adsp_disable
notice the c029ff68,we will use it with addr2line:
# arm-none-linux-gnueabi-addr2line -f -e vmlinux c029ff68 msm_adsp_disable /home/gnutoo/embedded/htcdream/SHR/kernel/linux/sound/soc/msm/adsp.c:1033
