Again. Can you please decode the code lines with

# addr2line -e vmlinux 0xc009ded8 0xc009de88

Please run the above shell command in the directory where your kernel
compile output resides. If you compiled with O=BUILD_DIR then cd to
$BUILD_DIR otherwise you will find vmlinux in the root of your kernel
source tree. Please provide the output.

Thanks,
