an update is available for your BIOS (6.18). If you update to this, does
it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

Title:
  046d:c52f [HP Elite 7100 Microtower PC] Kernel crash with Logitech
  K760 Bluetooth keyboard

Status in “linux” package in Ubuntu:
  Incomplete

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:

  Hit button 1 and wait a few seconds:

  Hit button 3:

  Hit button 1 and then button 3 without waiting long:
