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. > > > Kind regards, > > Paul > > > [1] https://bugzilla.kernel.org/show_bug.cgi?id=190871 Yes. We are debugging it there.
