I ran at least kernel 3.19 (Ubuntu Vivid), 4.0 and 4.1rc on 7437, and they have the same symptom - ACPI events are not generated with wireless hotkey presses and battery info is not updated. The commit 75646e758a0ecbed5024454507d5be5b9ea9dcbf is included. If I ran "cat /proc/interrupts", interrupt 9 (acpi) is not incrementing. If AC is plugged/unplugged, battery will be updated once. This implies AC event is generated correctly.
