What used to take 10-1= 5s on my system now takes around 3 minutes. A simple test is to break into ddb a= nd "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: at usbus0, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen1.1: at usbus1, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen2.1: at usbus2, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen3.1: at usbus3, cfg=3D0 md=3DHOST spd=3DFULL (12M= bps) pwr=3DON ugen4.1: at usbus4, cfg=3D0 md=3DHOST spd=3DHIGH (480Mbps) pwr=3DON ugen1.2: at usbus1, cfg=3D0 md=3DHOST spd=3DFULL (12Mbps) pwr=3DSAVE ugen1.3: at usbus1, cfg=3D0 md=3DHOST spd=3DLOW (1.5Mbps) pwr=3DON ugen1.4: at usbus1, cfg=3D0 md=3DHOST spd=3DLOW (1.5Mbps) pwr=3DON Regards, Navdeep
