Title:
Kworker use 100% CPU on Ubuntu 18.4-Kubuntu 18.04-Elementary OS Loki-
Fedora 27 and Debian 9
Status in linux package in Ubuntu:
Incomplete
Bug description:
I am Brazilian if it is possible to use a clear English thank you. I
am using google translator.
What runs it is that no matter what OS I use and where I install it, always
using Nouveau it gets this instability, and when using the NVIDIA proprietary
driver, it is not shown this problem but it gets stuck (locking).
I have not figured out how to solve it and all the colutions I find are not
the same as the ones I face.
So I'm reporting this bug.
