I'm not sure if there is no bug in drivers/acpi/button.c.
At least this driver never handles 0x02 sleep/power button notifications.
Just because there is no SCI routed to the drivers after a wakeup.

And we have quirks related to the freeze mode for 0x80 sleep/power button notifications.

I don't know if the above potential issues can cause real problems.
