Subject: IRQ nobody cared; Comm: swapper/2 Not tainted

Hi,

I just got this dump on my system. It happens occasionally, maybe once
a week. Result is that my USB keyboard and mouse (both Logitech
wireless) are laggy, mouse jumps across the screen and keyboard input
lags behind and creates multiple same keystrokes although the key was
only hit once.

Ubuntu x64 13.10, Ubuntu kernel 3.13.1 (issue has occured in past also
when using 3.10/3.11)
