Red Hat Bugzilla – Bug 1467289
fans full speed and crash after resume on thinkpad

Description of problem:
In Lenovo Thinkpad E540 with kernel version 4.11.6-201 after resume from suspend, fans start going to full speed and after few seconds the pc shuts down. The problem is still here also with newer 4.11.7-200
Version-Release number of selected component (if applicable):
4.11.6-201 (where starts the problem for me)
install Fedora 25 on a Lenovo Thinkpad E540 (don't know if also with other thinkpad models), and dnf update all the components
Steps to Reproduce:
1. Fresh install Fedora 25
2. dnf update
3. close lid (or suspend it in any way you prefer)
4. open lid (or resume how you prefer)
5. wait few seconds
fans start going full speed and after a while the computer shuts down
Fedora installed with LUKS encryption and LVM partitioning system default as it is proposed from the installation environment.
To identify the problem in the kernel I tried starting fedora from grub with kernel 4.8.6-300 (the one installed with Fedora installation), it has graphic problems (flickering, it was an old bug) but the resume works well.
Updating the bios not helped. Windows 10 in dual boot resume perfectly. Everything installed with UEFI and secure boot. Shutting down secure boot doesn't solve the problem.
The problem is still present even after the upgrade to Fedora 26.

this is the log from when I press the power button in order to suspend. until it resumes and crashes. I cannot find anything very strange but the problem is still here even after several updates.
I've downgraded the kernel to the version 4.8.16-300.fc25.x86_64 and here everything works fine. I don't have the time now to try every version from 4.8.16-300 to the 4.11.6-201 to see where started the problem. But it is clearly a kernel issue.
