Hi.

I tested 8-current(csup's at 2009.08.15.00.00.00).

kernel panic at boot time with some USB device.

ugen0.2: <C-Media Electronics Inc.> at usbus0
uaudio0: <C-Media Electronics Inc. USB PnP Audio Device, class 0/0, rev 1.10/1.00, addr 2> on usbus0
panic: lock (sleep mutex) Giant not locked @ /usr/src-8-2/sys/dev/usb/usb_request.c:312
cpuid = 0
KDB: enter:panic
[thread pid 16 tid 100036 ]
