ACPI keys quite work but are very laggy (in the order of seconds). Conclusion: I never experienced acpi interrupts flood in any case, in vanilla the interrupt count is much lower but then there are no interrupts even when I press acpi keys. dont_disable_ec_gpe_completely_at_storm.patch does not correctly fix the problem for me. When 2c81ce4c9c3 is reverted, call_psw_on_capable_devices.patch makes no difference as it still works well. Thanks. -- Guillaume
