[Bug 960322] [NEW] Degraded Raid 6 boot fails with "invalid arch independent ELF magic"

[Ian Macintosh]

Public bug reported:

To replicate: Create or build a server with sufficient drives for a Raid
6 array, remove one of the raid drives, and try to boot.

In my case I created an ESXi 5.0 VM with Ubuntu Oneiric 11.10 64bit
Server (ubuntu-11.10-server-amd64.iso) with 1 GB RAM, and 4 x 3GB
drives.  Manual setup, partition the 4 drives, Raid 6 them, create an
LVM vg with 0.5G /boot, 1G swap and the balance on /.

It installs and reboots without an issue.  I shut it down, removed
/dev/sda and tried to boot.

Fails with "invalid arch independent ELF magic"
