Bug Description
Upon resume in Intrepid (2.6.27.9-generic), I consistently get the following in my logs (from dmesg):

One problem I've been having is that the rt73usb module seems to get in a weird unusable state upon resume, but it's not mentioned in the stack trace so not sure if it's related issue or not. That issue is that my ralink usb wireless device is listed via 'lsusb', but shows up as DISABLED in lshw. The only way to fix is to unplug/replug the device, or remove and reinstall rt73usb via modprobe.
