Title:
046d:c52f [HP Elite 7100 Microtower PC] Kernel crash with Logitech
K760 Bluetooth keyboard
Status in “linux” package in Ubuntu:
Expired
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:
