It looks like the latest drivers, Catalyst 11.9 fixes the problem.

Can you confirm?

Hello to everyone.

Tryng to use the scan primitive, I founded it lock on my Radeon HD 5850. 
Loocking at the kernel source, I noted that the lock occurred in the latest 
pass and is caused by the branching, despite the block executed thanks to the 
OCL_PLATFORM_AMD macro. So I modified the kernel, and now it works on all my 
GPUs (HD 5850, GeForce 750M and GeForce 8800 GTS). The modifications are (lines 
indexes are the ones in attached file):
- remove all the brancing (commenting lines 123 to 142);
- changed the Step 1 procedure (commented line 145 and added lines 148 and 149);
- changed the Step 4 procedure (commented line 173 and added line 176).

Thank you for your work.
