the sample hangs in my box

Hi All,

I'm running Ubuntu 8.4. The GPU is HD3690 with fglrx 8.501 (ATI Catalyst 8.6),  and the sdk is v1.1-beta.

Firstly, I encountered "Locking assertion failure" error with the brook+ sample. I solved it by installing noxcb lib from  Then, I'm running hello_brook sample successfully.

Howerver, the simple_matmult sample hangs and I must reset the pc. When I set BRT_RUNTIME=cpu, it's running correctly.
