What CUDA driver version do you have? Was it updated recently?

I am facing the same Issue. I cannot even compile once. The code was fine a few weeks back.

When using the Nvidia driver version 381.22, I get occasionally get the following error:
"""
File "/global/scratch/rlehe/miniconda3/lib/python3.6/site-packages/numba/cuda/cudadrv/driver.py", line 296, in _check_error
raise CudaAPIError(retcode, msg)
numba.cuda.cudadrv.driver.CudaAPIError: [999] Call to cuLinkAddData results in CUDA_ERROR_UNKNOWN
"""
I now am pretty confident that this is due to the driver version, since I happen to have acess to a K80 GPU with driver version 381.22, and to another K80 GPU with driver version 375.26. The above error never occurs on the GPU with version 375.26, but does happen on the GPU with version 381.22. I also have access to a GeForce GTX 1080 Ti with driver version 381.22, and the same bug happens there. (hence the original title of the post, which erroneously attributed this bug to the GPU model)
Unfortunately the error is difficult to reproduce since it happens quite randomly. It typically happens when trying to compile a function, but (for our code which contains maybe 20 to 40 cuda-jitted functions) it does not always crash at the same function. (And quite often it does not crash at all.) Still, I thought I would still report it here, in case someone got the same error, or actually knows what causes it and how to fix it.
Thanks in advance for your help,
