I don't think there are (but you could try compiling 0.4b36 on FC6
just to confirm).

However, one piece of the puzzle did change: the scsi tape driver.
It could be as simple as having different default settings - like
the read ahead for example - or it could behave differently.

Or maybe the tape drive (the hardware) is just less tolerant on tape
errors. Maybe you should try swapping the tape drives just to see...
