Comment 3 for bug 1370368

I tried it here on a C6220 in the Dell lab and found the same thing. The tar'ed var/log dir is attached.

Notes:

## BIOS boot, not UEFI
## ubuntu-14.04.1-server-amd64.iso -> usb disk
## Add a second disk to array, hit ctl-I on way up and set up RAID1 array
## - exit, status of RAID1 disk is "Rebuild"
## Trusty Server install disk finds the raid 1 and seems to ask the right questions.
## Nope. fails to boot. ctl-alt-delete, reboot
## f11 to boot to usb drive (note: raid1 comes up with "degraded" status)
walk thru standard stuff (keyboard, network, hostname, login, encrypt home?, ntp, etc) until:
One or more drives containing MDADM containers (Intel/DDF RAID) have been found.
Do you wish to acivate these RAID devices?
## say yes
ne or more drives containing Serial ATA RAID configurations have been found.
Do you wish to acivate these RAID devices?
## say yes
## partitioner will come up with guided - use entire disk and set up LVM

## select Manual, follow above directions, still will not boot into hd
## at some point it asks where to install grub, select default
grub-install /dev/md126p1

## reboot, hangs, doesn't even seem to get to grub
