Bug Description

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". Linux crashed with:

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).

Hi,

I'm sorry to let you know that I'm not sort of responsible for this now.
But I do remember fixing similar problem. Check got.omapzoom.org project
hardware/ti/wpan.git under the Bluetooth compat directory. This occurred
because of one particular fix for l2cap_core.c was missing. So technically
not a TI issue....

Do you know who is responsible for the BT on the OMAP4/PandaBoard now?

I'll take a look. Do you know if this fix will get rolled in to the
ubuntu-omap-extras package?

Also, for running BT on the Pandaboard, is ubuntu-omap-extras the best
option? It seems a bit incomplete (e.g. having to run uim-sysfs manually
etc.).

Many thanks!

Yes. For now extras is the only way. But UIM can be put in rcS so that it
runs on boot.

Currently you can switch over to e2e forum for wireless connectivity
questions.
