Sorry, no idea... Maybe there has been an error during DKMS
installation so that the module was not replaced properly? But the
current module seems to be there in glxgears?

$ glxgears -info
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
GL_RENDERER   = GeForce GTX 750 Ti/PCIe/SSE2
GL_VERSION    = 4.5.0 NVIDIA 352.79
GL_VENDOR     = NVIDIA Corporation

That just works???

$ sudo modprobe -v nvidia-uvm
install modprobe nvidia ; modprobe -i nvidia-current-uvm $CMDLINE_OPTS 
insmod /lib/modules/4.4.0-1-amd64/updates/dkms/nvidia-current.ko 
insmod /lib/modules/4.4.0-1-amd64/updates/dkms/nvidia-current-uvm.ko 

$ lsmod|grep nvidia
nvidia_uvm             73728  0
nvidia               8540160  85 nvidia_uvm
drm                   356352  6 nvidia

I just did a reboot, started darktable -- again, with the openCL
errors -- tried glxgears, but now manually nvidia-uvm is loaded fine,
and after it is loaded darktable openCL works too.

Sorry, I jumped to a conclusion, this seems to be a different issue
than the previous bug report.
