I tried kernel 4.17.0-7.8 from cosmic on Ubuntu bionic and got some issues. After installing the 4.17 kernel, I tested my PC and found it can hibernate normally. But, later on I found the kernel was not compatible with Nvidia-driver 390.48 that was from Ubuntu bionic release. Purging and reinstalling the driver did not help. Then I added pa:graphics-drivers/ppa to install nvidia-390 (390.77) and it worked with 4.17.0-7.8 on Bionic. However, the hibernation problem came back and had exactly the same behaviour as before: the machine hanged on hibernation, my monitor went to sleep, the machine was still on(power button LED on and fans on), no response. I had to do hard reset.
