Package: Nvidia-kernel-dkms 
Version: 375.82-1
Severity: Important

Stretch point release 9.2 yesterday upgraded my machines from driver version 375.66 to 375.82-1. When running CUDA 8 compute tasks on a GTX1060 (3GB) the driver reverts from P2 state to P8 (idle) after approx 15-20 minutes. This can be seen using the nvidia-smi tool. Rebooting the machine will get it back to P2 state for another 15 or so minutes.

Updating one effected machine to 375.82-4 (in stretch backports) doesn’t help. The problem still persists. The point release updated 98 Linux apps including the kernel to 4.9.0-4 but not the CUDA app in question..

Is there a way to get the 375.66 drivers back?
