Description Bob Gustafson 2004-04-28 18:09:09 EDT
Description of problem:

  When I pull the bluetooth dongle (D-Link DBT-120) from the USB hole,
my system crashes. The mouse freezes, I cannot ping or telnet to box
from another networked box. Power cycle brings it back.

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

  It is probably somewhere in the hotplug USB bluetooth maze. All
components are from FC2-test3

How reproducible:
  Always

Steps to Reproduce:
1. plug in dongle
2. unplug dongle
3.
  
Actual results:
 When the dongle is plugged in, its power light is lit and some
stats/properties of the dongle show up in the
 'System Tools -> Info Center -> USB devices'
display.

Expected results:
 No crash, Info Center stats/properties go away.

Additional info:
  This has been reported before (months ago).

The problem seems to be quite common. 
I have ThinkPad T41 laptop with exactly the same symptoms. 
dmesg from Oops test in single user mode is included.

I have done a clean install of FC2 and have tested the Bluetooth
dongle insertion and removal works fine - no crash.

Now need to test whether the Bluetooth itself works, but that is
another bug report - if needed.

Works for me..
