I have this same problem, but I only have ufs1 partitions, all mounted r/w. It
seemed to appear about 3 weeks ago, so there has to be a commit in this
timeframe that caused it.
An extra inconvenience is that I always lose one or two files when I shutdown
due to ATA write caching - if I turn it off, I don't lose files, but my
system is too slow.
Doing a manual 'sync' before shutting down seems to help.
