To reproduce, connect a PS4 controller via USB. Now run "fftest" on it and choose effect number "0". While the effect still runs, pull the USB plug. Result: The kernel panics. Had to hard-reset the machine. Is it OK to just report this here or should I open a bug on Bugzilla for that? If more information is needed, just ask. Best regards, Manuel
