Hi, i can't reproduce here the errors Solar is getting.

Someone (i see Solar message) has hardware and time to help? We will 
make some tests in order to find out what is wrong in these boards.

Thanks.

1. i played a lot with the source code here. I agree it is slow, but it 
works on CPU and GPU, on self-tests and real cracking.
2. attached a new patch (it includes the new method of getWorkGroupSize 
information) as discussed in the list.
3. i'm more interested in new 7xxx AMD boards and Nvidia ones. Seems to 
be the best place to look for errors.

PS: magnum, do you have NVIDIA, right? Does it work in your hardware?
