I experienced similar problems last year and can empathize.
The following items improved my situation somewhat:
1) BIOS upgrade
2) Removing dual boot (I had both OpenBSD and Windows 2003 on one
machine. There were more errors if I did not power off after shutting
down Windows 2003 and just did a restart from within Windows. If I did
not unplug the machine after shutting down Windows, most of the time I
saw watchdog timeouts but if I powered off the host, and then powered
it back on, there were fewer errors)
I experimented with different combinations and different switches
(10/100/1000, 10/100, and 10-Base-T). When all the hosts connected to a
10/100 switch were running at 100 MB/s then changing nfe0 from
autoselect to full-duplex using
ifconfig nfe0 media 100baseTX mediaopt full-duplex
seemed to eliminate nfe0 hangs as well as timeouts completely. I am not
sure whether this has any rational basis or is specific to some weird
situation in my network, but that has been my experience.
