Hi All,

Unfortunately our company hasn't had the resources to help FreeBSD =20
much over the years, but I do want to say thank you to the folks who =20
are helping sort out this issue with the em driver.

That Intel gigabit interface is very, very common on server hardware =20
nowadays and it means a lot to us to make sure it (and FreeBSD 6.2 in =20=

general) are stable.

- mike
