I get a very reliable kernel panic when unplugging the USB sound adapter of Logitech G330 USB headphones/headset. I have not managed to get my hand on the actual trace as it shows up in none of the logs.
But I did grab a pics of the panic screen.
when connected to USB3 port:

when connected to USB2 port:

To reproduce, just unplug the headset and it will panic immediately every time.
