I don't know if this helps at all, as the problem is not with my siduction system, but with my aptosid one, but I have had the same problem for a while and had reported it in the aptosid forum (as linked above). (Since I had this problems, I am holding on DUIing my siduction system.)
Anyway, here is the system info:
