> Short: The attached patch fixes the bug-report #2139 from kernel bugzilla.

I wasn't quite convenient with the previous version of the patch, but I
just wanted to get it working at first and get some comments as to whether
the approach (put a workaround vs. blacklisting) is at all valid. Since no
objections arrived, I guess, nobody minds this small trick. So, I am
enclosing a reworked patch, which does essentially the same, but has some
more careful checking, and overall looks saner, than the previous one.
