The important part is:

resume device = /dev/dm-1

> /etc/suspend.conf

Don't exists.

BOOT_IMAGE=/boot/wmlinuz-3.2.0-2-686-pae root=UUID=d67c66b0-3bf4-4316-8e13-46e8551f292b ro quiet

Is here :-)

RESUME=UUID=81c6f99f-d571-497c-a6db-759f4beb0b2d

ummm (see below)

sda2_crypt -> dm-1
sda3_crypt -> dm-0

fdisk:

sda1 -> Linux -> /
sda2 -> Linux -> /home
sda3 -> swap

at /etc/initramfs-tools/conf.d/resume

Then,

I changed in /etc/uswsusp.conf /dev/dm-1 to /dev/dm-0 and now uswsusp works fine.
What is wrong at /etc/initramfs-tools/conf.d/resume?

Thanks for your help Jonas.
