Comment 3 for bug 1799235

The issue began after a fresh system install on a new computer. Admittedly, the first system I installed was Qubes, with Fedora (24 I believe). When I decided Qubes wasn't adequate for my needs, I wiped the system (reformatted using gparted) and installed the latest Ubuntu (as of a month ago). The kworker process was out of control in both Fedora and Ubuntu.

I have tried kernels 16, 17, and 18, latest as of about a week ago. 16 is no different than my current 15 (4.15). 17 and 18 show a 5% decrease in the kworker process. I haven't tried 4.19-rc8 yet because I thought rc was too rough for testing, but I'll try it on next boot. Am not hopeful that the problem is fixed. And, even if it is fixed in 4.19, that may not do me much good. I need virtualbox but I doubt it would run in 4.19. Plus I imagine there are more security vulnerabilities and compatibility issues with mainline testing kernels. It will probably take months to years for 18.04 to be using 4.19. Just a thought....

Best wishes,
Peter
