Hello,

I have problems with every newer driver than the release driver (8.921.2-120119a-132101E-ATI). I encounter the following problems with the OpenCL-Application:

Some tasks are not ending or send to CPU instead.
Often I encounter the message: "amdkmdap not responding and was restartet" (translated from german)
The screen is gone black and cannot be restored except of doing a reset.

System Information:

C2Q 9550 @ 3.4 GHz, Asus P5Q-E, 8GB, Win7 64 Bit, Boinc-Version 7.0.25

2 Gigabyte 7950 WF3 (not crossfired when using BOINC, second card has a dummy plug instead of a display)

No, it is really high cpu-usage according to the windows task-manager which shows usage up to 25 % on my quad-core for each milkyway process. Boinc shows 0.05 as expected. Please show also in my example wu in the original post. The cpu-time is very high!

I know the AMD drivers had the high CPU problem in 11.7 and 11.8 but I guess that could be different on different hardware. Does it happen with the current 12.1 drivers for you?
