syslog contains crashes like the following early in boot sequence:

2018-05-21T08:17:30.503136-07:00 INFO kernel: [    1.156700] cryptohome[197]: segfault at 8 ip 00005850d52b0d4c sp 00007fffa352bc30 error 4 in cryptohome[5850d529300

As discussed on  issue 701292  and https://crrev.com/c/870312, those segfaults are thought to be caused by that CL, which calls cryptohome too early.
