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 exhibits
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 poweroff
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 bug.
Whereas WOL, then power off manifests the bug.
