Hi,
Sorry, it's only to report that your arn't the only one.
Just upgraded the drivers to 334.21 and ran into the same issue yesterday. In
my case - Debian 7 - a driver upgrade doesn't upgrade die OpenCL packages and I
did it manually.
Last time I had also troubles to get openCL working again. IIRC removing all
nvidia and opencl related packages and reinstalled them did it.
I had no time to try this now.
