When you can't use write barriers as XFS tell you in the logs, you better switch of write caching for the harddisks / raid controller, unless you happen to have NVRAM or safe power supply. But then using write cache without barrier should not make any difference unless you actually have a crash or power failure during write operation. Did you test with ext3 as well? You wrote it crashes with ReiserFS (version 3) even faster. When it crashes with several filesystems its unlikely to be a filesystem issue.
