One and off, yes. There was a timing issue I remember ... I had a 2.4 patch in my oss directory that worked fine for 2.4. I don't remember if the same patch worked ok in 2.6. I didn't have much time to debug it, but I remember when I put a few debug prints in the hpt init routine, the problem went away, indicating an initialization timing issue.
