The 'timed out in command phase' message probably indicates that you have a cabling or termination problem. It means that the bus has probably gotten stuck in that phase, which isn't good. So check your cabling and termination. FreeBSD shouldn't freeze, and it's possible that the issue that causes the freezes has been fixed in a later version of FreeBSD, but I don't know for sure. In any case, the best way to fix your problem is to track down the cabling or termination problem in your system.
