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:
Confirmed
Status in linux source package in Zesty:
New
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. Without any sleep/suspend the laptop's fan is
basically "off" or silent, even for hours.
The bug has been fixed upstream, see
6625914 ACPI / EC: Drop EC noirq hooks to fix a regression
9c40f95 Revert "ACPI / EC: Enable event freeze mode..." to fix a regression
and/or https://bugzilla.kernel.org/show_bug.cgi?id=196129
(with duplicate https://bugzilla.kernel.org/show_bug.cgi?id=191181)
and I hope this fix will make its way into a near-future kernel update
to ubuntu :)
Many thanks!
