[OpenAFS] Windows client stops working with Bluetooth adapter attached to client workstation

[John Perkins]

We've run across one user who is using a computer with a USB Bluetooth 
adapter attached and running the OpenAFS client for Windows (1.5.68 
right now, to be updated to 1.5.72 this evening).

The symptom the user has reported is that the computer appears to hang 
when logging out.  The afs_init.log indicates something funky going on 
with the network interfaces:

3/15/2010 11:05:04 AM: Mountpoint[1] = .cs.wisc.edu%cs.wisc.edu:root.cell.

...and the computer will sit, apparently frozen, for hours at this point. 

This appears to be similar to the behavior reported and commented on in 
this post 
http://www.openafs.org/pipermail/openafs-info/2009-February/030926.html

The computer in question has 2 wired interfaces (only one in use) as 
well as the MS Loopback Adapter and the Bluetooth adapter installed.  
The wired adapters are Realtek PCIe GBE Family Controller adapters. 

The user in question was using a different computer that had only one 
wired adapter with an NVIDIA nForce Networking Controller installed.

Is this likely due to the unused wired network adapter or the Bluetooth 
adapter?  Any other suggestions for how to avoid such problems?

afsd_init.log available upon request (or I could send it on to 
openafs-bugs if that is more appropriate).
