25 why the kernel was tainted is shown after the Process ID ('PID:') and a shortened
35 You'll find a 'Not tainted: ' there if the kernel was not tainted at the
36 time of the event; if it was, then it will print 'Tainted: ' and characters
42 the kernel got tainted earlier because a proprietary Module (``P``) was loaded,
43 a warning occurred (``W``), and an externally-built module was loaded (``O``).

63 	 * Externally-built ('out-of-tree') module was loaded  (#12)
