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.
