Bug ID: 208033
Summary: r8169 wake-on-lan (WOL) works only after a manual
suspend/resume cycle
Product: Networking
Version: 2.5
Kernel Version: 5.6.15
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other

Hi !
I have a weird problem with wake-on-lan on my Realtek card.
After turning wake-on-lan flag on (using either ethtool or NetworkManager), to
make the PC responsive to wol packets I have to first suspend and wakeup it
once manually (hitting any key or power button).
After this maneuver, I can wakeup via magic packet from all subsequent suspend
transitions AND also from the first shutdown. Then I have to repeat the manual
suspend/resume cycle to make it work again.
A similar problem was mentioned at
https://forums.centos.org/viewtopic.php?t=71861, but the proposed solution
(forcing autonegotiation on) didn't work for me.
The PC is a Gigabyte NUC-like barebone:
https://www.gigabyte.com/Mini-PcBarebone/GB-BLCE-4105R-rev-10. BIOS is
up-to-date and doesn't show any "obvious" wol settings.
Here's some infos (just ask me if more are needed):
