bandwidthTest segfaults

We have two Tesla M2070s with CUDA 4.0 and driver 270.41.19 with rhel 6.1 and gcc 4.4.5. We are able to build and run deviceQuery with no problems and we are able to build bandwidthTest. However, when we run bandwidthTest, it segfaults. In fact every sample in the SDK we have tried has segfaulted, as well as our own cuda programs which run well on other platforms (with cuda4 and fermis). We have rebooted, reloaded the driver, rebuilt the SDK and toolkit – nothing seems to help. Any suggestions?

Check the power connections to the GPUs

Thanks – we reseated the card and that seems to have done the trick
