      OpenCL and ATI CAL crashes system when HD 4870x2 and HD 5870 used at the same time

      Hi,

      I just installed ATI Stream Software Development Kit (SDK) v2.01 and ATI Catalyst™ 10.2 driver. In my system I have HD 4870x2 and HD 5870. When I run an OpenCL or ATI CAL application , and two graphic cards are simultaneously utilized  system crashes. If I disable one card (i.e. I remove its connection to lcd display) applications run fine. Situation is repeatable with sample applications present in ati stream sdk. 

      Previously (in sdk 1.4 and sdk 2.0) I didn't has such a problem. I wonder whether this is related to my system or is it a bug of stream sdk 2.01 or catalyst 10.2?

      Does anyone else also experience same problem?

      What can I do to remedy problem (other than reverting back to old versions of sdk and catalyst)?

      thx in advance
