Comment 1 for bug 612224

I can also confirm this issue. I recently installed two servers both with two 500GB drives configured using raid 1 with Linux software raid.

The installation goes smooth all the way but when I reboot afterwards I end up with a busybox and a nonworking raid setup.

If I partition the drives and create the raid using a Mandriva 2010.1 disc and then install Ubuntu 10.04 on top pf those partitions it works just fine.

I'm very surprised to see that the mighty Ubuntu distro is having such serious bugs, I hope this gets sorted out quickly!
