Please try the patch below. Hi, Yes, this patch helps, but I think there is still a problem. I think that trim needs to be done after CONFIG_BUILD_DOCSRC and possibly after CONFIG_SAMPLES are built. At least CONFIG_BUILD_DOCSRC seems to cause this error: Setup is 16508 bytes (padded to 16896 bytes). System is 6125 kB CRC 8aa70f94 Kernel: arch/x86/boot/bzImage is ready (#9) ERROR: "cn_del_callback" [Documentation/connector/cn_test.ko] undefined!
