By way of confirmation, I'm running 2.6.24-19-generic. While playing sound through the headset, I bumped the connector, and got the crash below - this is unusual on my system. The device is .. Bus 004 Device 007: ID 046d:0a0c Logitech, Inc. dmesg says this - from when I originally plugged it in (time+1021), to when I bumped it (time+2176), to when I plugged it in again (in a different slot) (time+2184).:
