Summary:
Issuing authrestart reboots the machine, but it ends up at the pre-boot login screen, preventing remote access.

Steps to Reproduce:
1. While logged in, enter fdesetup supportsauthrestart, which returns true, indicating authrestart is supported.
2. Enter 'sudo fdesetup authrestart' and enter superuser password, followed by password for FileVault user.


Expected Results:
Pre-boot login screen should get bypassed, and the regular login screen should appear.

Actual Results:
Pre-boot login screen appears, and machine is no longer accessible remotely (via ssh or screen sharing.)

Version:
El Capitan 10.11 (15A279b)

Notes:


Configuration:
Occurs with a MacBook Pro (mid 2009), which reports "true" when queried with fdesetup supportsauthrestart.
