[ 256.280000] ext4: Unknown symbol crc16 (err 0) This issue happens on Build Bot Snapshots and Own Compile (from today SVN Source) ... the modules aren't loaded in the correct order.

Jan 14, 2009 · Hi Roland, Thanks a lot for replying. Below I have written details of experiments we did and our understanding. Problem: insmod failure for externally compiled module :- Experiments: (1) Compiling 2 modules a.ko and b.ko ( dependent on a.ko ) together :- Works (2) Copying Module.symvers from module "a" dir to the module "b" dir, before compiling b.ko :- Works.. I looked into what happened a bit. Someone was cleaning things up in Linux, and after their cleanup they saw that no module code in the kernel tree called putname() anymore, so they un-EXPORT_SYMBOL'ed it. It's still accessible to builtin kernel code, but not loadable modules. Regards, - Rob.

I've been struggling and haven't been able to get kernel modules built using the 4.4.x configuration to load against it. The toolchain is available for it, but the linux-4.4.x package is 4.4.59. I tried using the synoconfig there against 4.4.180 "stock" but the modules kerplode when I try to load them.

The syntax of the insmod command is very simple; you just type insmod, followed by the module filename. For example, to load the md5 module, we can use the following command: Sometimes modules depend on other modules. In these cases, if you attempt to load a module that depends on others that aren't loaded, insmod will fail.

run a uname -a make sure the kernel version matches if so do a ls /usr/lib/modules and display the results. Im guessing the kernel might have upgraded and youre missing the recent source.

0004710: "Unknown symbol in module" when booting freshly installed system Description I freshly installed a new CentOS system (my first) using [1], but after rebooting it will fail to load several important modules with "Unknown symbol in module".

insmod uses the .modinfo section for the following: It contains the kernel release number for which the module was built.

I solved this issue in the end, I recompiled the kernel, recopied over the modules and created a symlink between 3.15.0 to 3.15.0+ ... this + was not added to a file for some reason which messed up alot of things adding this I was able to make and install modules.

Like @WayneWWW mentioned, you seem to have a module compiled for a different kernel config, and this is likely in turn why other symbols are missing (there are probably two reasons for the module to fail, rather than just version/configuration it was compiled against).
