Hi again again,

It hung after the 10th hibernation...

I wonder if the problem would not be of Debian's uswsusp binary, because tty1 
tells me that the image is successfully loaded but I just can't act on my box 
afterwards.

There is a bug open in the Debian BTS requesting a packaging of the new 
upstream version (0.8) but the maintainer is told to be too busy to handle it 
for now.

Don't know...

Regards, 

Didier
