Public bug reported:
System hangs during boot with 4.4.0-45-generic if cryptab contains a
valid entry. Passphrase prompt never seen. Black screen with blinking
underscore in upper left corner. Repeated attempts to type passphrase
have no effect.
There are two workarounds:
1) Comment out line referring the encrypted partition in /etc/crypttab and
/etc/fstab. Mount the partition manually after boot completes
2) Boot in 4.4.0-42-generic which works as do earlier versions. i.e. the user
provides passphrase at the prompt during boot and the system finishes booting
