regression: oops with usb bcm203x bluetooth dongle 2.6.5-rc3-ben0

[Soeren Sonnenburg]

Hi.

This dongle used to work fine (at least till 2.6.3).
While this kernel version does not have the same issues that rc2 had
with usb (not recognizing devices again once they are
removed/reinserted), this dongle gives me an oops on _insert_.
Mass storage devices seem to work fine.

This is on a ppc machine with xmon support compiled in. So if you need
more infos than this backtrace, please say so.

Soeren.
