this behavior repeats on a modern version please fill a bug report

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).
