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

[Chas. Owens]

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:

    Jul 31 07:25:01 LD-cowens kernel: [ 199.114124] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5

Then I hit button 3:

Hit button 1 and wait a few seconds:

    Jul 31 07:25:47 LD-cowens kernel: [ 244.558409] power_supply hid-00:1f:20:3d:cf:09-battery: driver failed to report `capacity' property: -5

Hit button 3:

Hit button 1 and then button 3 without waiting long:

Chas. Owens, as per http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareIndex.jsp?lang=en&cc=us&prodNameId=4132190&prodTypeId=12454&prodSeriesId=4132189&swLang=13&taskId=135&swEnvOID=4059#120 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.

[Chas. Owens (chas-owens)]

There seems to be no (obvious) way to upgrade the BIOS from Linux. The output of the command you requested is
