The kernel crash logs

Description of problem: If you were to connect a bluetooth device and then let it automatically disconnect through inactivity or just switch it off, there is a risk of the kernel crashing due to the sysfs object associated with the particular device still existing.


Version-Release number of selected component (if applicable): 3.3.4-1


How reproducible: After a bluetooth device goes on a connect-disconnect cycle a few times


Steps to Reproduce:
1. Connect a bluetooth device
2. Disconnect it
3. Repeat a few times
  
Actual results: Kernel crashes, but not completely, dmesg shows the extent of the damage but it does not seem to crash the computer entirely.


Expected results: The kernel should not crash and should be able to remove sysfs objects associated with a bluetooth device when they disconnect


Additional info: The bluetooth dongle used is:
