Some errors reported by cryptohome.  Unclear if this is because there is no TPM on this system

(also took a look at it)

For build 3377, the same test (vm_test / login_OwnershipApi) passes, but shows the same cryptohome messages.

I'm not sure why it rebooted.

Since this was a VM test, I wonder if there might have been something helpful in the qemu logs (if any?), but I didn't find them.

ran the tests locally, cryptohome errors seem to be a red herring.

 Issue 878888  has been merged into this issue.

Green for days. Closing
