Description of problem:
Kernel seems to be randomly crasing when trying to connect to bluetooth device or trying to create network over bluetooth

How reproducible:
Seems to be easy to reproduce just requires time

Steps to Reproduce:
1. get a bluetooth device (in this case openmoko)
2. try to connect to it trough bluetooth using various ways like bluetooth networking pand etc...
3. get a vmcore from kdump
Actual results:
please wait... (determining panic task)

Comment 1 James 2009-02-01 12:30:04 EST
I see this with kernel-2.6.29-0.74.rc3.git3.fc11.x86_64. It happens immediately after adding a new device via the GNOME BlueTooth applet's "Setup new device" wizard.
Comment 2 James 2009-02-01 18:40:07 EST
Another note: the i686 version of the same kernel doesn't seem to have a problem, at least for the USB dongle and phone I tested. Either way, I think this bug's severity should be changed to High as it takes down the whole system.
Comment 3 James 2009-02-17 04:40:10 EST
I've not seen this in kernel-2.6.29-0.33.rc5.fc10.x86_64 so far.
