CPU averages: 5.3.0-19: 2.03W, 99.6% idle, 0.1% in kernel, 93.5% in C10 state, 5.3% in C8 state, 1.66GHz 5.3.0-23: 13.71W, 99.3% idle, 0.1% in kernel, 92.3% in C10 state, 6.1% in C8 state, 2.05GHz
GPU averages: 5.3.0-19: 0.10W 5.3.0-23: 7.19W ACPI thermal zone: 5.3.0-19: 38.92 C 5.3.0.23: 68.65 C So, not much difference in CPU loading or in C10/C8 states, but it is clocked faster on the -23 kernel and is 11.7W more power being consumed. The GPU is also consuming far more power in the -23 kernel. The ACPI thermal zone is ~30 degrees hotter, hence the fan activity. Given the kernel changes I provided made no changes, this looks like a i915 regression somehow. I'll see what has changed there. -- 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
