I'm seeing similar issues with a quad port 82546EB card, and they're not
using MSI as far as I can tell; IRC 28-31. MSI's are >127 or so I
think?

Don't see TSO in ifconfig options, but will issue an ifconfig em3 -tso
to see if it makes any difference.
Interestingly I can pull 30-60MB/s to/from em0 (LAN) without any
problems, but pulling 5MB/s from em3 has repeatedly led to the interface
just going silent until I bounce it. Quite intermitent though,
sometimes it dies in the first second or two, sometimes I can pull down
20GB without a hitch.
