Loading module Error: Version magic ' 2.6.32-504.el6.i686 SMP mod_unload 686 ' should

Before I also encountered this problem, and later I solved, but did not record, and now met, I was the whole day, so now recorded, for later reference;

I started to load the module when reported such an error:

Hello:module_layout:kernel tainted. Disabling lock debugging due to kernel tainthello:version magic ' 2.6.32-504.el6.i686 SMP mod_unload 686 ' should is ' 2.6. 32-504.el6.i686 SMP mod_unload modversions 686 '

The first two lines of error are kernel contamination, which is usually not passed during validation, or there is no simply no write Module_license () validation. I started writing about Module_license ("Dual BSD/GPL");  Verification Pass but later I changed to: Module_license ("GPL"); It is possible (in fact, the sense of the beginning of the verification is also possible, and then I experimented with the next).

As for the second error, your kernel tree version is inconsistent with the version of the kernel you are running. Can refer to this man's: http://blog.sina.com.cn/s/blog_752fa65f0100p6wc.html; and this man's: Http://blog.sina.com.cn/s/blog_ 6e5e78bf010105jj.html

I will share my solution and steps here (in fact, as the man mentioned);

The first step, look at the version of the kernel you are running: ls/usr/src/kernels/2.6.32-504.12.2.el6.i686/, which is stored in the corresponding version of your kernel source code, which I personally understand. Since there is nothing in the starting/usr/src/kernel/directory, I am through the command: Yum install kernel-headers kernel-devel gcc gets to. Available through Rpm-qa | grep ' kernel ' command to view these kernel-related packages, or you can use the Uname-r command to view the information of your kernel version, but it is strange that the version information I get with uname-r is not the same as/usr/src/kernel/, The brother who wished to know was told. (It is possible that Uname-r displays the run version number, not the kernel detail version number);

Below is Rpm-qa | The grep ' kernel ' command displays:

Kernel-2.6.32-504.el6.i686kernel-headers-2.6.32-504.12.2.el6.i686kernel-firmware-2.6.32-504.el6.noarchdracut-kernel-004-3 56.el6.noarchkernel-devel-2.6.32-504.12.2.el6.i686

The second step, look under your kernel source tree, ls/lib/modules/2.6.32-504.el6.i686/-l; paste only two soft-connected files below

lrwxrwxrwx.  1 root,     09:52 build,/home/kernel/linux-2.6.32lrwxrwxrwx.  1 root root     09:52 Source-/home/kernel/linux-2.6.32

I do the kernel of the source tree is: linux-2.6.32;

The third step, modify the configuration in the makefile file, modify the following:

obj-m:=hello.o#kerdir=/lib/modules/$ (shell uname-r)/buildkerdir=/usr/src/kernels/2.6.32-504.12.2.el6.i686curdir =$ (shell pwd) All:         make-c $ (kerdir) m=$ (CURDIR) Modulesclean:        make-c $ (kerdir) m=$ (CURDIR) Clean

Now basically, the other solution is to look at the link to the man above;

If there are errors, please correct them and grow together. Thank you!!
