The only partion not encrypted on my system is /dev/sda1, i.e. /boot.
Thus, /dev/sda2 is the LVM PV which contains /, /home, swap and four
others /mnt LVs.

No busybox rescue prompt, after having failed for three times cryptsetup
again starts asking me for the passhprase and after three more failures
the system "blocks" (but I still see what I type) on:

=====
cryptsetup: maximum number of tries exceeded
Done.
Being: Waiting for root file system... ...

[then, after about 5min something like the following]
/dev/mapper/vggismo-lvroot not available.  Check `cat /proc/modules`.
Dropping into a shell.
=====

And the machine restart :-(

Booting with the "break" kernel option (as suggested at bug #466573 [1])
causes the machine to reboot before prompting for the cryptsetup
password, at least with kernel 2.6.25-trunk-amd64.

I added the four modules you suggested (dm-mod, dm-crypt, sha256 and
aes) to /usr/share/initramfs-tools/modules, regenerated the initrd, but
nothing changed.

Thx, bye,
