    While being a small patch, 16.2-16.3 was a large change. It removed the very
    aggressive starvation avoidance of spin on wait waker/wakee in 16.2, which
    clearly helped your issue.

    Pretty sure we have another spinner. A reniced -11 batch run of top -d 1 and
    vmstat during the spinning, and a kernel profile for that time will be
    helpful.
