State-Changed-By: yongari 
State-Changed-When: Thu Dec 4 04:36:10 UTC 2008 
State-Changed-Why:  
I think this issue might be fixed in HEAD. Would you try fxp(4) in 
HEAD? (Replacing fxp(4) with HEAD version would also work on latest 
stable/7).

State-Changed-Why:  
Feedback timed out(> 15 months). I believe the issue was fixed 
long time ago. If you still can reproduce the issue on recent 
FreeBSD, please let me know.
