Subject: hibernate a system booted from external USB drive - is it posible ?

I wonder, whether it is expect to work with current stable kernel 3.3.2 or 
not. Seems not to work here (s2ram works fine).
Hibernate however writes data to the swap partition, but during wakeup I get :

kernel: PM: Hibernation image partition 8:6 present
kernel: PM: Looking for hibernation image.
kernel: PM: Image not found (code -22)
kernel: PM: Hibernation image not present or could not be loaded. 

and the system continues with normal boot. In addition there's a message from 
swapon, that a suspend data signature was found and that is is overwritten 
with the swap signature.

:-(
