Pixel (madebypixe...@proton.me) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |madebypixe...@proton.me --- Comment #2 from Pixel (madebypixe...@proton.me) --- Hello, Here is my experience. I am using an LG Gram 14Z90Q-G.AA76B and have faced high CPU usage from kworker threads on every distro I have tried (Fedora, ArchLinux, VanillaOS, Ubuntu). From my experience, there is a somewhat reliable way to temporarily stop the high CPU usage. I don't dualboot windows, so I cannot test the suggestion of booting from windows to linux. Rather, I have noticed the following pattern: 1. Plug In USB-C cable (charging/HDMI) 2. Run "top" to verify that 3 kworker threads appear with high CPU usage. The fan will eventually kick in 3. Suspend the laptop (close the lid, press power button, press Fn+s, or manually suspend) and wait for the fan to completely turn off. Optionally unplug and plug in USB-C cable (sometimes helps). 4. Wake device from sleep. 5. Run "top" again, kworkers will be gone Now this does not work 100% of the time, as sometimes after waking from sleep the device still keeps the kworker threads up and running, but eventually after doing this they disappear until the next reboot. This workaround gets the job done for me, as long as I don't have to reboot often. -- You may reply to this email to add a comment.
