Title:
  Kernel crashes in rt2x00queue_get_entry+0x24

Status in linux package in Ubuntu:
  Expired

Bug description:
  When using an Logilink USB WiFi stick reported as  Ralink Technology,
  Corp. RT5372 Wireless Adapter, I ancounter frequent disconnects
  despite good wifi signal, and repeated kernel crashes at
  rt2x00queue_get_entry+0x24.

  The crash may happen from time to time, but can be provoked by heavy
  wifi traffic.

  Maybe it is a problem with the drivers state management, because dmesg
  shows resets or replugs of the device if temporary disconnect happens.
  So I think the device may reset due to other problems (eg. flaky usb
  power), and the driver doesn't handle it well in all states. Maybe the
  above function is called with the device already disconnecting.
