Updated my NAS from 4.5.3 to 4.5.4 and now I cannot use my Nvidia GPU for Hardware Transcoding because /dev/nvidia-uvm is missing so CUDA doesn't work. Anyone else hit this and know of the fix?
Newish to QNAP but feel like I might need to slow down on the updates. I normally like to keep ontop for security fixes but seems they don't test stuff very well either. If I look in the Nvidia Driver update notes they are all about how they broke the drivers with a new firmware and now they've fixed it. I feel like I might be stuck waiting for a driver update...

I'm seeing the same missing nvidia-uvm.
Any progress on this?

Anyone opened a ticket for this?
QNAP does not come here..so tickets need to be opened

Seems to be random, done a few reboots and sometimes it's there and others it's not. I'm not touching it for the moment as I've got it back working.
They really need to update the driver though also as this older driver is blocking some things from working also
