--- Comment #26 from Cy Schubert <cy@FreeBSD.org> ---
(In reply to Michel Marcon from comment #25)

I am a committer. I will commit it when one last bug in the patch has been
fixed. After using WOL to wake a bge equipped system, the next power off is=
 in
fact a power cycle (poweroff/poweron, similar to a reboot but you hear the
system power off for a second or less). Do you experience this bug when you
applied the patch?

The bug manifests itself on Acer laptops equipped with bge0. My Acer exhibi=
ts
the behavior but doesn't under Windows. I must conclude that the patch still
needs set or clear a bge register.

Let me know if your system experiences the poweroff/poweron bug if you powe=
roff
or halt -p anytime following a wake from WOL.

The bug does not manifest itself if the machine is rebooted before poweroff=
 or
halt -p: i.e. WOL the system, reboot, then power off does not exhibit the b=
ug.
Whereas WOL, then power off manifests the bug.
