Wysocki" , len.brown@intel.com Just bisected it. I also tried linux-acpi-next/test, and no change. The sympthoms are that EC does't sent any GPEs, and therefore battery insert/removal events don't show up. It can be see by doing 'grep . /sys/firmware/acpi/interrupts/*' With regression the line is shown like this: /sys/firmware/acpi/interrupts/gpe1C: 1 enabled Without regression it is /sys/firmware/acpi/interrupts/gpe1C: 22889 enabled and steadily increasing. After suspend/resume, regression disappears. Best regards, Maxim Levitsky
