Don't have any other evidence than the case I was describing.

Yes, it had nothing to do with soft updates at all and that's why I had the "remained after" in the sentence. > > Don't know is it fixed or not as I don't have necessary hardware at > > the moment.

Ok, I definitely had problems only with R5, but you certainly know much better what it was exactly. I'll need to lend 50-pin SCSI cable and test vinum again.
