Network crash

I'm running the release version of 2.0 unpatched; not tested on prior 
versions.  My Dell Inspiron 8000 laptop has 3 nics: dc0 (xircom 
cardbus), xl0 (built-in) and aue0 (3com usb nic).   I have a dlink 
wireless router attached to the 3com usb nic.  The laptop is running as 
a router to the internet.  I can ping the dlink from a pc on the local 
network, but when I try to http to its admin interface, DF crashes with 
the following error:

OpenBSD works on this same hardware.  See dmesg below and let me know if 
you need anything else.
