error with cuda_extra.cu
Hello,
I'm on ubuntu 16.04
Here is my configuration and the error message:
 * VERSIONS:     XMRig/2.3.0-beta1 libuv/1.8.0 CUDA/8.0 gcc/5.4.0
 * CPU:          Intel(R) Core(TM) i5-6400 CPU @ 2.70GHz x64 AES-NI
 * GPU #0:       GeForce GTX 950A 42x15 f:0 s:0 arch:50 smx:5
 * ALGO:         cryptonight, donate=5%

I get: 
GPU 0: the launch timed out and was terminated
/home/user/xmrig-nvidia/src/nvidia/cuda_extra.cu line 246

During make, I get the following warnings:

and towards the end, another warning:

I tried purging cuda and reinstalling then recompiling but still get the same warnings and the miner doesn't work.

Any help is appreciated.

Also, a big thanks for the amazing work you're doing. I'm already using your CPU version, seriously the best miner ever. I hope you'd release the amd version soon.
