After restarting cgminer, second GPU gets very slowh hash [SOLVED]

[amuleth]

I couldn't find any solution yet except restarting the computer. It is getting very annoying each time. Do you have this problem too?

I see this too in a dual GPU system. The only fix I have found is to lower the TC on the offending GPU. With a high TC, it seems that the core and memory clocks get stuck at their idle values, leading to 10-20kh and an unusable system (its the primary GPU).
