[Bug 1768315] Re: Kworker use 100% CPU on Ubuntu 18.4-Kubuntu 18.04-Elementary OS Loki-Fedora 27 and Debian 9

2018-05-04 Thread Joseph Salisbury 
Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Uma screenshot do htop.

** Description changed:

  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.
