Issue with Canon 600D and raspberry hangs

Hi,

I am using some rigs with a raspberry connecting to a Canon 600D camera.
These are, you wouldn't guess, used for making long running timelapse 
recordings.
However, after a while (be that 1 to 2 weeks) the camera becomes 
unresponsive.

Lately I found out that the command "gphoto2 --reset first" solved the 
issue temporarily and the
setup continued making photo's, however not for long.

Rebooting the raspberry resulted in the system becoming unresponsive and 
staying offline.
Everything had to be manualy rebooted to get things working again, 
camera and computer..

Anyone familiar with this issue?

The version I am using is gphoto2 2.5.17
Latest version rasbian..
