Bug Description
System hangs during boot with 4.4.0-45-generic if /etc/crypptab 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
robert@kalymnos:~$ cat /etc/crypttab
spare2 UUID=498b08bb-
robert@kalymnos:~$ grep mapper /etc/fstab
/dev/mapper/spare2 /spare2 ext4 defaults 0 2
