The problem is still there in GIT as of this morning, which
includes 8e92b6605da989 ...

Comments on why bc71bec91f9875ef825d12104acf3bf4ca215fa4 seems
to be causing this?  I think it's just bad reports getting to
userspace, rather than an actual 120K wakeups/second.  (The
report is of course not always 120K, but it's usually in that
range.)
