PrimeGrid: Nvidia driver 295.xx problems

[RSS]

We are seeing an elevated error rate from hosts using Nvidia drivers 295.xx.If your monitor is put to sleep by the computer, the GPU is no longer available as a CUDA device. This will cause an immediate failure of any CUDA WUs. This includes GFN/Genefer, PPS Sieve, GCW Sieve, and llrCUDA.In the mean time we can only suggest not to upgrade to this version (or downgrade if already installed), or disable power saving in the system.We will update once we have more information.
