Hello munbi and thanks for this bug report. I marked the other two bugs you filed as duplicates of this one, and added "tasks" for the packages you filed the other bugs against. One bug report can track a problem across several packages, so there's no need for multiple reports.
I don't think xserver-xorg-video-amdgpu is really involved here. If you can reproduce this issue without logging it to the graphical console, i.e. by calling `sensors` from tty, and you agree that this proves that Xorg is not involved, then please change the status of the xserver-xorg- video-amdgpu task to Invalid. My feeling is that we're seeing a kernel issue here. If you can reproduce it with Hirsute (the current Ubuntu devel version) then I think we can add a "regular" kernel task, as the problem is not HWE- specific. Currently linux-image-generic 5.10.0.14.16 is in the Hirsute -proposed pocket. Could you try to test that newer kernel and report how it behaves? I'm setting the status of this bug to Incomplete for the moment, waiting for the results of your testing. ** Changed in: linux-signed-hwe-5.8 (Ubuntu) Status: New => Incomplete ** Changed in: lm-sensors (Ubuntu) Status: New => Incomplete ** Changed in: xserver-xorg-video-amdgpu (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910562 Title: Fans switching on and off every 10 seconds after update to kernel 5.8.0-34 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1910562/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
