Public bug reported:
The system does not wake up properly the SSD when resuming from suspend
(hibernate works fine).
It may matter that this SSD has a password to be entered at bootup;
perhaps it would be necessary for the OS to send this password again to
the hard drive during resume.
The problem still occurs with upstream kernel:

The current default configuration for Ubuntu is to disable hibernation
and enable suspend in menus because, supposedly, there are some systems
on which hibernation does not work. The maneuver to re-enable
hibernation in menus is nontrivial (requires editing polkit-1 files).

Christopher M. Penalver (penalvch) : I do not remember the first version
that was installed on this laptop (was it 11.04?), but I know that no

[Dell Latitude E6230]
I'm sorry but I do not remember which was the first Ubuntu release
installed on this laptop (would there be some kind of update log

I tried a 12.04 bootable USB stick.
The laptop immediately boots the USB stick without prompting for the
hard disk password (normally, it does so just before Grub).
After Ubuntu is booted, the hard drive is not accessible. dmesg shows
many errors as follows:

Interestingly, I've noticed that in Windows 7, the suspend to RAM button
is greyed out (no explanation given as to why).
