uath panic on insert.

Hi

I get this panic on insertion of a uath USB dongle.

On amd-64:

uath0: <Atheros Communications Inc USB WLAN Device, rev 2.00/0.01, addr 3> on us
bus1


Fatal trap 12: page fault while in kernel mode

The i386 panic is only slightly more useful:
ugen4.3: <Atheros Communications Inc> at usbus4
uath0: <Atheros Communications Inc USB WLAN Device, rev 2.00/0.01, addr 3> on us
