Comment 9 for bug 191119

Reading the original report here, I think it is a possibility that the problem was caused by grub overwriting part of the fakeRAID control area. A contributing factor may be a hardware environment that causes different drive orders to be recognized by BIOS, grub and kernel(s).

I don't know this for a fact but I offer it as a suggestion for an area to investigate. If so, this would mean it is a different problem to bug 568183
