The problem seems to occur after kernel updates. NetworkManager needs to
be restarted ('sudo kill PIDforNetworkManager") after suspend.

Not sure if this will help, but I've experience this on the 3.16 kernel & I've
put the syslog & kernlog info on pastebin:
http://paste.ubuntu.com/10242534/
and attached.

Given that this seems to be related to Intel, I should add that I am
using the video drivers via the intel graphics installer:

Ubuntu 14.10: with no other changes, upgrading to the 3.19 kernel from:

works for me.

Re my comment #31: changed back to 3.16 kernel and the problem
reappears: boot, wait for black screen, reboot w/Ctrl-Alt-Del, grub
appears, encrypt login appears, continue to boot normally. 100%
reproducible. Definitely looks to be a kernel issue.

@Joseph: I don't recall which 3.6 kernel - it's a fairly recent install
on a test laptop. I have the following installed:
$ dpkg -l | grep linux-image
ii linux-image-3.16.0-32-generic 3.16.0-32.42
i386 Linux kernel image for version 3.16
Correction:
"@Joseph: I don't recall which 3.6 kernel"
should be: @Joseph: I don't recall which 3.16 kernel

@Joeseph: sure - give me some time to clean out /boot & I'll test them
shortly. Note: I can only test the 32bit kernels as I do not have 14.10
installed on a 64bit yet.

Tried all three: rc2, rc3, rc6 and all of them prompt for the passphrase
properly. I powered down between each boot to ensure that they weren't
prompting following a reboot (as previously reported). I'll try rc1 and
3.15 to see if I can reproduce with any of those.
