Bluetooth Dongle (HCI mode)

Code for a CSR bluetooth chipset appears broken in recent kernel
releases. After a device is paired the kernel panics. This has been
tested with a dozen USB dongles / systems and is consistently a
problem. On the rare occasion it might not cause a kernel panic
although it will definitely still crash after a few minutes. This
does not happen with older kernel releases.

What kernel version is crashing, and what is the exact text of the
kernel panic?

Please let me know how I can help solve this issue. We have lots of
dongles and can try and get any information needed to fix it.

You might want to ask the Linux bluetooth developers (now added to the
cc of this response.)
