This issue still exists with latest LTS, Linux 3.2.0-35-generic #55-Ubuntu SMP Wed Dec 5 17:42:16 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
This workaround with bt_coex_active=0 works, but a more permanent fix should be found.
The related bug has been closed, but it has not been fixed. One of the final comments in that thread : "the problem is that BT devices on some platforms behave well with Intel's WiFi and on some platforms they don't"... not really a solution.
