I've also been hit by this (with a clean gnumach-1-branch GNU Mach, only
enhanced by an smashing stack protector patch) and reported it at
<http://savannah.gnu.org/bugs/?18349>.  For me it wasn't with high
network load, though.  I was sshing to the GNU/Hurd box and compiling a
package there when the kernel decided to panic.  But perhaps that SSH
traffic has some similar pattern to what you have experienced.
