Hi Colin Ian King, I tested the revert kernels from here https://kernel.ubuntu.com/~cking/lp-1853044/.
The results from Powertop can be found here https://postimg.cc/gallery/TTmWSfX. I also included the latest 5.3.0-61 kernel for reference. The test system is an XPS 9550 with HD Graphics 530, Intel Core i7 6700HQ For all kernels I booted up, ran powertop, waited to idle and made screenshots. Hope this helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853044 Title: 5.3.0-23-generic causes fans to spin when idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853044/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
