If you have an oops or BUG of any sort, I think that sets the taint flag
for further oops reports, because after the first one you can't really
trust that the stacktrace or internal kernel structures aren't
corrupted.  Most of the time they aren't, but you simply can't trust
that.  So I'd expect the first one to be untainted, and then subsequent
oops reports to have the taint flag set.

Of course if you start loading random kernel modules that didn't come
with the kernel itself, you can also taint the kernel.  If you have
staging drivers loaded, you'll have the taint_crap flag set because
staging drivers are crap.
