Possible problems with Broadcom BCM5704C 10/100/1000 on Tyan Motherboard

We also have these boards, I've found them unusable under
FreeBSD/5.3-STABLE with 8GB of RAM--other qualities appear to work okay.
But I even saw some infrequent problems with 6GB.

FreeBSD/amd64 is not in my opinion not actually a stable tier 1 quality
release under these configurations, too many problems remain--especially
in regards to ia32 emulation.

Exigencies of the moment forced us to forgo further debugging and adopt
linux/amd64.  (Sadly, some people actually have to get work done on their

To anyone who wants to peg these problems on hardware, running linux these
machines have operated without fault while under a mix of high
computational and i/o load.   moreover, the machines were tested
extensively using memtest+ in a controlled ambient temperature range from
60F to 80F.

This is a really lamentable situation.  We've been a primarily FreeBSD
shop for 10 years now and for the past 4 years or so a pure FreeBSD shop.
Switching to linux on just these machines has been quite the headache but
I'm holding on to the hope that FreeBSD/amd64 will shape up.

FYI, most of the positive reports I've seen regarding FreeBSD and this
motherboard are 2GB setups.  In my own testing that arrangement worked
_very_ well.

Addendum: The RAM timing is a bit marginal on the second processor.  i.e.,
          RAM that runs fine under extensive memtest+ ing has trouble
          doing 400MHz DDR on the Second Processor.  We ended up running
          it at 333MHz DDR
