+Some vendors distribute binary modules (i.e. modules without available
+source code under a free software license).
+As the source is not freely available, any bugs uncovered whilst such
+modules are loaded cannot be investigated by the kernel hackers. All
+problems discovered whilst such a module is loaded must be reported
+to the vendor of that module, <I>not</I> the Linux kernel hackers and
+the linux-kernel mailing list. The tainting scheme is used to identify
+bug reports from kernels with binary modules loaded: such kernels are
+marked as "tainted" by means of the <TT>MODULE_LICENSE</TT> tag. If a
+module is loaded that does not specify an approved license, the kernel
+is marked as tainted. The canonical list of approved license strings
+is in <TT>linux/include/module.h</TT>.<BR>
+"oops" reports marked as tainted are of no use to the kernel developers
+and will be ignored. A warning is output when such a module is loaded.
+Note that you may come across module source that is under a compatible
+license, but does not have a suitable <TT>MODULE_LICENSE</TT> tag. If you
+see a warning from <TT>modprobe</TT> or <TT>insmod</TT> for a module
+under a compatible license, please report this bug to the maintainers of
+the module, so that they can add the necessary tag.
