So, I got my TS-7200 back, and v1.3 from NetBSD doesn't change anything
on my system....  It is interesting that pings while at the RedBoot
prompt do work, but when I try to ping when FreeBSD is booted, I get
the following errors:
epe0: ed_stat: 0x92000003mbuf: 0xc0e2f700 len: 74, next: 0xc0cd5000, 2<pkthdr>,

Though considering that RedBoot and FreeBSD are probably sending
different response packets, it's probably unsurprising that pings at
RedBoot work...

Jesse, have you tried to send the exact packet that is listed above to
see if your system can handle it?  It seems to happen at certain sizes..
A reverse namelookup at either 80, 83 or 84 bytes in total length
triggers it, though lengths 81, 82 and 85 seem to work fine...
