Hi,
Resume-from-suspend stopped working in HP xw6600 in fedora kernel
4.10.8-200.fc25.x86_64, while it worked just fine in
4.9.9-200.fc25.x86_64.
When powering on the suspended PC, there is no video output, and to
recover, I need to reset the machine.
Nothing is recorded in the journal logs for the resume, last lines are
from the suspend:
Apr 08 15:41:49 xw6600 systemd[1]: Reached target Sleep.
Apr 08 15:41:49 xw6600 systemd[1]: Starting Suspend...
Apr 08 15:41:49 xw6600 systemd-sleep[6675]: Suspending system...
Also tested 4.11-rc5, but it fails the same way.
Bisection leads to commit:

hwmon: (coretemp) Convert to hotplug state machine
Install the callbacks via the state machine. Setup and teardown are handled
by the hotplug core.

If I do "modprobe -r coretemp", then the resume works OK with
4.10.8-200.fc25.x86_64.
Any ideas?
