What used to take 10-15s on my system now takes around 3 minutes. A simple test is to break into ddb and "call doadump" with or without this rev. I have a serial console on this machine and so I can use ddb whether the attached USB keyboard works or not. Here is the usbconfig from the machine: ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen1.1: <UHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen2.1: <UHCI root HUB Intel> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen3.1: <UHCI root HUB Intel> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen4.1: <EHCI root HUB Intel> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen1.2: <product 0x7000 vendor 0x0557> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen1.3: <USB Multimedia Keyboard BTC> at usbus1, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON ugen1.4: <USB-PS/2 Optical Mouse Logitech> at usbus1, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON Regards, Navdeep
