Subject: [REGRESSION 4.17] Spurious wakeup / reboot with power button

Hi,

we've got a regression report since 4.17 about the behavior of
power-off with the power button.  When a machine is powered off with
the power button on desktop, it reboots after a few seconds instead of
power down.

The manual power down via "systemctl poweroff" works fine, so it's
possibly some spurious wakeup by the power button action, and some
ACPI-related change is suspected.
The regression still remains in 4.18-rc3.

The information is found in openSUSE Bugzilla:
  https://bugzilla.suse.com/show_bug.cgi?id=1099930
Feel free to join there.

Let me know if anything hits your radar.

Thanks!

Takashi
