freebsd stable - Mar 2005 - bge0 watchdog timeout

Twice today during very heavy network I/O (dumping a large postgres 
database over the ethernet to another machine on the same switch) I got 
this error:

Mar 22 03:42:22 d01 kernel: bge0: watchdog timeout -- resetting
Mar 22 10:28:24 d01 kernel: bge0: watchdog timeout -- resetting

The most informative info I found searching google was this one:
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/net/2003-08/0096.html

However, that seems to imply that a 5.4-PRERELEASE build March 15 would 
not be caused by this particular bug.  The dmesg says this of bge0:

bge0: <Broadcom BCM5704C Dual Gigabit Ethernet, ASIC rev. 0x2003> mem 
0xfc9b0000-0xfc9bffff,0xfc9c0000-0xfc9cffff irq 24 at device 9.0 on 
pci3
miibus0: <MII bus> on bge0
bge0: Ethernet address: 00:e0:81:2a:ac:5e


Any insights on where to look?  This is a dual Opteron running 
FreeBSD/amd64 with 4GB disk.

The only thing funny I did was build with CPUTYPE=opteron 
optimizations.  I'm rebuilding right now without that, but I've also 
cvsup'd the sources...  This is my SWAG as to the problem.

Anyone else still experiencing these timeouts?

For the archives:  I punted and installed an em based NIC and disabled 
the bge on board via BIOS.  Stable ever since.  See thread in 
freebsd-amd64 list "tyan k8sr lockups" for full gory details.
