Comment 5 for bug 1530252

I also observe fan problem after suspend / resume. Hardware is Dell Latitude 5501.

Restarting i8kmon fixes the issue.

A possible workaround is to restart i8kmon whenever the laptop comes out of suspend:

$ cat /etc/systemd/system/i8kmon-after-resume.service
[Unit]
Description=Restart fan monitor after resume to keep laptop from melting.
After=suspend.target hibernate.target hybrid-sleep.target

[Service]
Type=simple
ExecStart=/bin/systemctl restart i8kmon.service

[Install]
WantedBy=suspend.target
