Hi,
Since upgrading to either of these drivers from 384.111, I get a frequent kernel hang on my Linux 4.13 / 4.15 system with a GTX 770.
There is an Ubuntu bug report here, but I will copy the relevant info below: Bug #1767932 “nvidia-390 causes kernel hang” : Bugs : nvidia-graphics-drivers-390 package : Ubuntu
4.15 + 390.48 hung task:

In the meantime I am upgrading to 396.24, but do not expect it to be resolved.
