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.
