System is an IBM Netfinity 4500R- 2x PIII SMP, ServeRAID 3L, 1G RAM. If I'm not mistaken, the other instances of people experiencing this were also SMP boxes. I'm not sure at what point it 'resolved itself,' but it's possible my kernel and world were out of sync, or that I skipped doing a mergemaster.... is now working with 5.2-CURRENT as of Jan 1.... Not sure this helps in any immediate fashion, but another data point.... Scott
