I got several WU error out with "Maximum elapsed time exceeded", all with an elapsed time around 1166 seconds. As far as I can see the reported elapsed time is credible, it matches the timestamps logged into successive workunits.

Example :

http://albert.phys.uwm.edu/result.php?resultid=57388

To complete the WU, my card would need ca 4500 seconds elapsed time. Yes, the CPU load is very high indicating something's wrong (Oliver mentioned a driver bug already), still it would be nice to see if at least the results would validate.

OK, by manually editing the client_state.xml file (not recommended), I managed to make one task complete in time:

The GPU utilization is around 75% (not bad!!!).

OK, I have also managed to finish three tasks by editing the client_state.xml as suggested by Bikeman.
One WU 18877 is still pending. The other two (17950 and 16677) have already validated - one against another OpenCL WU and one against a CUDA WU.
