This is caused by the fact that you have 2 RAID0 volumes on the same disk set.
I think this has cropped up before but I can't remember the bug.
The normal thing to do is to have an entire RAID0 set and then partition the disk to create your separate portions for your different OS.
If you were to create a single RAID0 set and partition that set it would work fine, I think this is what the other guy did in the other bug.

Did this setup work in previous Linux installs?
