Comment 0 for bug 1709616

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

and I hope this fix will make its way into a near-future kernel update to ubuntu :)

Many thanks!
