=== Obtaining the ti_3410.fw file needed by ti_usb_3410_5052 ===

Debian (and perhaps other Linux distros) do not package ti_3410.fw (no, not even in lfirmware-linux-nonfree). The following bash script will use git to obtain just the one file from kernel.org and move it to where "modprobe ti_usb_3410_5052" will find it:

#!/bin/bash
sudo apt-get install git
git clone -n git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git --depth 1
cd linux-firmware
git checkout HEAD ti_3410.fw
sudo cp -p ti_3410.fw /lib/firmware

The script is tested on Debian with 3.1.0 kernel and will need to be modified if your system uses RPM and/or does not follow the standard filesystem hierarchy.

This appears to be a known issue with how IPIs are handled within the generic SMP infrastructure. A fix is being discussed on [https://lkml.org/lkml/2012/2/19/11 LKML], but the warning appears to be benign.
