Hi !

Good to know that I'm not alone :D.

Well, basicaly, we should identify the source of our problem. This can be done by :

  • identifying the compilation options and looking for differences between the configuration file of the 4.12 and 4.13 branches (those file can be found in /boot/config*)
  • comparing the kernel options on boot, visible in your /boot/grub2 or /boot/efi/grub2 grub.cfg file. By I don't expect to see any difference in here.

Unfortunately, I don't have time to investigate on this :(. Anyway, as the drain is very similar to the one we had without disabling WOL on the Ethernet Card (mine uses r8168 driver), I tend to suspect this driver. If you've got time, try to read the changelog and identify the changes between the two series, about the ethernet driver and the wifi driver (mine is rt8723be).

As you mentioned it, if the drains is absent when forcing the shutdown through the power button, we should incriminate the poweroff procedure. There's maybe a network service that restarts the network service, without reloading our handwritten service that disables WOL.

Hi there,

I encounter a serious bug since the update of the 4.13 series kernel in Fedora 26. While everything worked as expected before the update, after upgrading to 4.13.3 on my laptop, i encounter the following issues :

  • My Realtek rtl8723be driver (rtlwifi) changed, and so i needed to change the parameters given to modprobe
  • I noticed a battery drains while off line since the update (that was solved before because it was a problem with the wake on lan functionality, that was previously always enabled).

If you also encounter this kind of problem, keep me updated, i'll take time to fill a bug.

In order to obtain information on what is blocking, you should put an eye on the file : /var/log/messages.

During the shutdown, pressing "Escape" should display information on the monitor, and so what operation is taking so long. We cannot help without those information.
