I'd be happy to get this set up in the lab for you to look at, but at 
the moment, all of our lab machines are in use (I rolled this box over 
to a community project after buildworld "cleaned" it up). I try to 
provide hardware resources to FreeBSD committers and developers hunting 
down problems, and at the moment, I'm at the limit, there's no hardware 

As soon as something becomes available, I'll drop you a line and get 
this onto a test server. Generally, I create a VRF for each test 
environment with outside access via ssh and an internet connection for 
fetching whatever may be necessary (most often 10mbps). OpenVPN access 
is also available depending on what the committer/developer wants.

Thank you again for your interest in this anomaly (for lack of a better 
description). I'll get something up for you as soon as a box becomes 
available. Any preference on platform (considering this did not seem to 
be platform dependent)? I can do sparc64, amd64/x86-64, itanium2, and 
i386/x86-32. The environment I'm experiencing the problem in is x86-32, 
and I think someone is almost done with a DL580-G3, so I can roll that 
out when it becomes available.
