A reliable test
case I found is trying to FTP to ftp.astron.com - never works.

I'm experiencing the exact same problem. tcpdump show bad checksums like Nathan, ftp ftp.astron.com doesn't work.

My nic is:
em0: <Intel(R) PRO/1000 Network Connection Version - 6.2.9> port 0xcc00-0xcc3f mem 0xdfde0000-0xdfdfffff irq 18 at device 2.0 on pci1
em0: Ethernet address: 00:11:09:35:c3:81

Using a vanilla FreeBSD 6.2 kernel on Gentoo/FreeBSD, networking is working. On #gentoo-bsd we're trying to find the origin of the issue.
