Guo:

Thank you very much for the very detailed response on the meaning of the
oops - it was very educational for me. I did have one question, however.
How were you able to identify the relevant section in the source code?

As Steven points out, this could be a bug in the overlayfs code. After
getting a 2nd oops last night, I rebuilt 3.5.2 w/o overlafs in order to
test that theory. Though I am unable to reproduce at will, 2 oopses in
60 hours suggests I should not have to wait too long for a verdict.

I will follow-up in a couple of days one way or the other.
