Two things: - Like mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=191181, the bug happens in other Lenovo models as well. It's not limited to the X1 Carbon 5th Gen. - The bug was fixed in kernel 4.13 but not in 4.10. This means that users who run the HWE kernel on Ubuntu 16.04 LTS will have this problem too!
I can reproduce it on my local system which has "linux-image-generic- hwe-16.04" installed (4.10.0.32.34). Reading through the comments, it's not exactly clear to me which of the commits has fixed this problem, but I guess that the following two changes have made the difference: https://patchwork.kernel.org/patch/9835823/ https://patchwork.kernel.org/patch/9835825/ So, will this bug be reopened or should I create a separate issue for the 16.04 HWE kernel? ** Bug watch added: Linux Kernel Bug Tracker #191181 https://bugzilla.kernel.org/show_bug.cgi?id=191181 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1709616 Title: CPU fan goes full throttle triggered by waking up from suspend on Lenovo X1 Carbon (5th Gen., 2017) Status in linux package in Ubuntu: Triaged Status in linux source package in Zesty: Triaged Bug description: Thinkpad X1 Carbon 5th generation ultrabook with i7 Kabylake CPU running Ubuntu 17.04 has its fan go full steam if the laptop is woken up from sleep/suspend.
