[Kernel-packages] [Bug 1957808] Re: Kernel soft lockup after resume
Hi Thomas, thank you for the help to gather more information. I added "initcall_debug" in grub and tested the suspend / cpu-lockup problem after a rebooting into the new grub config. I tried it different times, and can say, that the connected Thunderbolt dock was not the problem, as the cpu-lockup also happens, when the laptop was not connected to anything. It is not happening on each suspend, but after some rounds of suspend+resume I can see the problem. In the attachment is the kern.log with two incidents, the last one took quite a while (8000s). If you have any other idea or have things I can test, I am happy to help!

That's because the GPU does not enter RC6 any more. For example, my Thinkpad P50 (6th gen) idles at 9w with current 5.3 kernels. Previously, it idled at 5W. Effects on a T480 (8th gen) are less dramatic but still significant. 5.5RC1 has the maintainer's second pass at this, which restores RC6 idling The maintainer's patch for 5.3 is here: https://gitlab.freedesktop.org/drm/intel/issues/614#note_366057 I have applied this to tag Ubuntu-hwe-5.3.0-25.27~18.04.2 and it builds. I am testing it now. I think it would be very helpful to backport this if you can.
