Description
The pod nvidia-device-plugin-daemon stays in CrashLoopBackOff.
I have an old nvidia GPU in the test machine, so i don't know if this is the problem here.
My GPU is VGA compatible controller: NVIDIA Corporation GF106GL [Quadro 2000] (rev a1)
TNS version: TrueNAS-SCALE-21.04-MASTER-20210418-092917
