After upgrading an Ubuntu server from Maverick to Natty ( grub2 version 1.99-rc1-13ubuntu3 ) the system no longer will boot. Grub complains about the raid5 array: 

error: Found two disks with the index 0 for RAID md0
error: Found two disks with the index 1 for RAID md0
error: Found two disks with the index 2 for RAID md0
error: Superfluous RAID member (4 found)
error: Unknown filesystem
This is a 4 disk raid5 array that mdadm still recognizes and looks fine, with each disk having IDs 0 through 3 respectively. Despite the fact that it complains about the raid, it still shows the LVM logical volumes in the output of ls. The array is the sole LVM PV.
Bug filed at https://launchpad.net/bugs/776422. Any hints on how to proceed with debugging this? Is there a way to check what modules are built into the core image from the rescue shell?
