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?

It goes black and disappears off the screen with a lot of other text
so I'm unsure.

This text you are seeing in probably the crash dump of the failure, could you
try to take a picture of the screen so we can check if there is some useful
information there.

Also if the kernel doesn't panic instantly you could check if there is some
issue in the kernel log after pairing and save it somewhere so we can take a
look. Use the 3.8 kernel.
