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.) - Dave
