Re: 2.6.12-rc1-mm4: oops in sysfs/symlink.c

Howdy,

I get the following oops when I switch a Logitech USB Bluetooth Hub
into HCI mode (hid2hci utility):

usb 1-2.1.1: new low speed USB device using uhci_hcd and address 5
input: USB HID v1.10 Mouse [Logitech USB Receiver] on usb-0000:00:04.2-2.1.1
hiddev0: USB HID v1.10 Device [Logitech USB Receiver] on usb-0000:00:04.2-2.1.1

run hid2hci:

usb 1-2.1.2: new full speed USB device using uhci_hcd and address 6
