Timming can be if you have one of the drives having seek problems. The Panic you describe is typical bad drive behavior. If drives are new and not server drives the media has not been checked for flaws. So any smart tech activity like remapping may through off the timing. This is were I use SpinRite, to check media. You also need to watch for how the jumpers are set on these older units,too, makes a difference.
