Yes; it has been working quite fine for me with 7 up to a release-candidate. In 7.0-RELEASE you must disable the hptrr driver because it eats the device. See: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/120615 http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/120842 When I say "working fine", this is with 8 SATA drives (6 of them in a raidz2, two of them for other stuff) and not having any issues like corruption, timeouts or whatever else people have had with shaky controllers. However, I cannot speak to performance because it's a PCI-X card that I've plugged into a PCI slow, so throughput is limited by the PCI bus (and the machine is otherwise not the fastest to begin with). Note that this is on 32 bit; haven't been able to try it on 64 bit because I the PCI-X card wouldn't work on the motherboard (again PCI, so it's hit-and-miss) where I would otherwise have tried it. I'd love to find a buyable PCI-E version that also worked in FreeBSD... I'll see if the link in your post contains any such hints. -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@infidyne.com>' Key retrieval: Send an E-Mail to getpgpkey@scode.org E-Mail: peter.schuller@infidyne.com Web: http://www.scode.org [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEABECAAYFAkiZ30QACgkQDNor2+l1i31dpACgnSgvtHU/zkIi9sJl4irUGcaa 5s4AoK/nkNVJqsgIGd7Wzxhj97mydh3p =EEas -----END PGP SIGNATURE-----
