re(4) watchdog timeouts after a short time

I upgraded my 2.1-DEVELOPMENT box from 2.1-DEVELOPMENT from several
months ago and my re(4) a RTL8101E card only works for a few seconds
after boot.  After which I get watchdog timeouts and am unable to ping
a remote host.  I was unable to get any information from tcpdump.
Here is the relevant verbose dmesg output and sysctl output.  I have
tried disabling rx/tx csum and vlan{mtu,hwtagging} all to no avail.  Let
me know what further info is needed.
