When using nvidia-drivers from 358 and 361 series, switch from xorg to text console and back results in a semi crashed system.
Xorg crashes with process stuck at 100% of one core/thread while doing nothing (strace shows no activity).
SSH to system is still possible but there’s no way of restarting/killing X or even removing nvidia/nvidia_modeset kernel module.
The only way to get back to X is with hard reset.
Everything works as expected with driver version 355.11 and earlier.
