   - ''scp'' your new kernel module to the PM3 and load it with ''insmod your_module.ko''. If it fails, check ''dmesg'' to see what's wrong.
+==== Problems ====
+If you fail to load a kernel module and dmesg shows something like the following:
+<code>
+version magic '4.9.166-fsl-imx-INIT-004+ preempt ARMv7 p2v8 ' should be '4.9.166-fsl-imx-INIT-004 preempt ARMv7 p2v8 '
+</code>
+<code>
+version magic '4.9.166-fsl-imx-INIT-004-dirty preempt ARMv7 p2v8 ' should be '4.9.166-fsl-imx-INIT-004 preempt ARMv7 p2v8 '
+</code>
+Then double check:
+  * That ''CONFIG_LOCALVERSION_AUTO=n'' is set in ''.config''.
+  * That your ''make'' command has the option ''LOCALVERSION= ''.
+  * That you have no uncommitted changes according to git.
