Title:
16.04.1 LTS hang during boot 4.4.0-45-generic with /etc/crypttab.
Boots fine in 4.4.0-42-generic and older
Status in linux package in Ubuntu:
In Progress
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
