  Running a Pandaboard rev A3 with Ubuntu 12.04.1 LTS with the ti-omap4
  kernel.  Have set up bluetooth (bluez) and was able to see the
  pandaboard via bluetooth in the Mac's "Set up Bluetooth Device".

  I'm running the following kernel:

  3.4.0-1489-omap4 #18-Ubuntu SMP PREEMPT Tue Dec 11 10:06:12 UTC 2012
  armv7l armv7l armv7l GNU/Linux

  I happened to have hcidump -X running on the console, it looks like
  the Mac was doing a SDP browse.  Here's the full output of the hcidump
  -X followed by the kernel oops (actually, there's a second oops
  following the first).
