I just saw a mail fly by on linux-bluetooth and linux-serial mailing lists that seems to be a patch one person made that alleviates the issue.
I'm not sure of all the archive areas for the mailing list but as I get from the mail list, look for this message with patch attachment: Date: Sat, 6 Jul 2013 10:43:43 +0200 From: Gianluca Anzolin <gianl...@sottospazio.it> To: linux-blueto...@vger.kernel.org Cc: linux-ser...@vger.kernel.org, hol...@ahsoftware.de, pe...@hurleysoftware.com Subject: [RFC] PATCH: rfcomm tty refcount fixes -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165433 Title: Kernel 3.8.x panics on bluetooth DUN disconnect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165433/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
