NVIDIA dev driver 260.x - error
FYI - maybe go on the FAQ, my system running Ubuntu 10.10 with NVIDIA Dev Driver 260.19.21 and I get this error:

[s]tatus [p]ause [r]esume [h]elp [q]uit => ERROR: clEnqueueReadBuffer() -5

Change to NVIDIA dev driver 256.53 and no error.

Hope this helps others out?

I have GTX470.


I've seen -5 errors on Windows too, which were related to gpu instability.
256.53 - the best for Linux
258.96 - the best for Windows
They are the last drivers which were proper.
fixed in oclHashcat v0.25
