I have spent some time with this and isolated my problem to the SSD drive that
I was using.  I have not determined why the SSD drive had caused an issue, but
after installing an WD3200BEVT-00AORTO and letting the laptop churn for days I
have not been able to reproduce my original problem.

Lastly, find / -xdev -inum 8668611 -print did always produce the fault, the
issue was in man page directories (I don't remember the exact path).

Consider this resolved for me.
