The closest common ancestor is, then, /, right?
UTSLing makes me think that fstatvfs1() - the syscall that fails in
your ktraces - does stuff walking up/down the directory tree, unless
certain flags are given. I'm beginning to suspect that something is
weird with / when the system is hosed. It sure looks to me as though
the errors occur for, and only for, things that read / (as opposed to
searching it), as if it loses its world read bit or some such.
The real baffler to me is how logging out fixes it. Do you have a
program that just does a stat() and prints out the results? Siccing
that on / might reveal something interesting.
