CUDA error cudaStreamSynchronize(stream) and CUDA error in ComputeBondedCUDA

Main board GA-X79-UD3 with two 680 GPUs
OS: Debian10 Linux, kernel 5.10.0-19-amd64
OpenGL 4.6.0
nvidia driver 470.141.03
Months ago, following updating/upgrading of amd64, the GPUs, while rendering correctly, became unable to run classical molecular dynamics simulations. Launching a minimization with software NAMD with both GPUs or with one of them (by software or even by removing one GPU)

namd2 +idlepoll +p12 +devices 0,1 min.conf
namd2 +idlepoll +p12 +devices 0 min.conf
namd2 +idlepoll +p12 +devices 1 min.conf

NAMD organizes the simulation correctly but at the stage of starting the computation, a crash occurs with error (for example with GPU 0)
TCL: Minimizing for 3000 steps

I had no hint from both NAMD and Debian forums

Thanks for advice
