Maybe you haven't enabled softupdates on those partitions..FreeBSD used to default to using a slow, but safe method of doing disk writes; Linux defaults to a fast, but incredibly dangerous method which is likely to give you disk corruption in the event of a power failure (these two have different disk access patterns by virtue of the different algorithms). Softupdates gives you the best of both worlds.
