That does the trick.  After 100 passes of adding and deleting the test 
bridge the problem does not occur.
In my prior testing it never made it more than 6 times through and 
usually would panic in first few tries.

I'll send a patch to this list so the fix can be back ported to our OOT 
driver.

Thanks,
