I believe the oops is related to USB HID device support, which I didn't use in 2.5.7 but enabled for 2.5.8, after which the oops happened. > Which USB device did you remove when the oops happened? The HID device in question is the Eizo monitor which has a builtin USB hub, which disconnects when the monitor is turned off and produces the oops. Regards, Udo.
