Interestingly, if I enable WOL by hand with ethtool (even though ethtool is showing it as already enabled), it works.

/sys/class/net/laneth0/device/power/wakeup shows "disabled" if I let systemd enable WOL via the .link file, but after doing it manually with ethtool it shows "enabled."

Note that all I have done is switch to the HWE kernel - I am using exactly the same verison of systemd, ethtool, etc. Has something in the kernel stopped implicitly configuring the system power management, either generically or for r8169? Is ethtool doing it explicitly?

Aha ..

https://github.com/systemd/systemd/blob/master/src/shared/ethtool-util.c#L279

Reads current WOL settings and doesn't set them again if not necessary - we're back the r8169 driver or the BIOS possibly not quite initializing something correctly on start-up, which an explicit ioctl to set WOL corrects :(
