I have SR1630HGP server with 2 network adapter.
FreeBSD 7 see only 1 network card (82574L), but 82578DM is not.
I download and install http://downloadcenter.intel.com/download.aspx?url=/17509/eng/em-6.9.21.tar.gz&DwnldId=17509&lang=rus Network Adapter Gigabit Base Driver for FreeBSD* 7.x and OS see 82578DM.
But after that when i shutdown my server (shutdown -p now) - it reboot, not shutdown.
I install driver like write in README:
Edit /boot/loader.conf, and add the following line:
Also i disable em in kernel.
I try to update to FreeeBSD 8.0 - but is steel reboot, not shutdown
PS if i disable if_em_load="YES" in loader.conf - FreeBSD shutdown OK.
I can confirm that FreeBSD 8 (8.1-RELEASE) works fine on SR1630HGP.
Just make sure you include the acpi driver *in* the kernel with your amd64, or the kernel will reboot at boot.
