Actually this is the more relevant changelog; it can be seen that 9.1 will definitely have the new driver from LSI: http://svnweb.freebsd.org/base/releng/9.1/sys/dev/mps/mps.c?view=log Also I'm not completely sure the mps(4) driver can be backported to kFreeBSD 9.0. I think getting kFreeBSD 9.1 into wheezy-backports very soon after Wheezy is released would be the best plan. Regards, -- Steven Chamberlain steven@pyro.eu.org
