Title:
  Kernel crash with Logitech K760 Bluetooth keyboard

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I have a Logitech K760 Bluetooth keyboard.  This keyboard has three
  buttons that allow you to connect to three different machines via
  Bluetooth.  I have button three mapped to my Ubuntu box.  When I hit
  button one and then quickly hit button three, the kernel crashes.  If
  I wait a long period of time, it does not crash.  The logs (see end
  for full trace) seem to indicate that there is a problem with the
  kernel trying to create file that already exists:

      sysfs: cannot create duplicate filename
  
'/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.7/2-1.7:1.0/bluetooth/hci0/hci0:21'

  I assume this is happening because the kernel has yet to clean up
  after the disconnection before the device tries to reconnect.  My
  current workaround is to wait a while before hitting button 3 when I
  accidentally hit button 1.  It would be nice if I reduce the timeout
  before the kernel cleans up the after the device to shorten the period
  of time I have to wait.

  Here I have hit button 1 and waited a few seconds:

  Then I hit button 3:
