encrypted partition being skipped or booting too fast

[Jason Paul Joines]

    I'm using Kubuntu 12.04.2 with encrypted root and swap partitions
along with an unencrypted boot partition.

    Sometime within the past couple of weeks, hibernate functionality
disappeared.  I'm not sure when because I usually use sleep and only use
hibernate occasionally.  I figured a recent update had changed something
but had no idea what.

    Then I noticed that my swap was not active.  The "swapon -a" command
failed with the error, "swapon: /dev/mapper/sda2_crypt: stat failed: No
such file or directory".  This was easily remedied with "cryptsetup
luksOpen /dev/sda2 sda2_crypt".

    The next time I rebooted I was prompted for my password for the root
partition which functioned normally, then for the swap partition. 
However, as soon as I typed the first character of the password for the
swap partition the machine booted and swap was not active.  I rebooted
again and discovered that after prompting me for the swap partition
password, the machine would boot pretty quickly even if I typed nothing
at all.  In each case I can activate swap manually but it doesn't get
activated at boot.

    Any ideas?
