Comment 49 for bug 941874

I've just installed a HP Microserver (N40L) with the latest installer from precise-updates/main/installer-amd64/20101020ubuntu136.9/images/quantal-netboot. The installer fails to activate the raid, so I had to drop into a shell, write dmraid -ay, to continue the installation.

After the install, I have the exact same problem, I'm always dropped into the busybox initramfs shell, write "dmraid -ay" to activate the raid, and "exit", and boot continues as normal.

I've solved my problem by adding the line "[ -x /sbin/dmraid ] && /sbin/dmraid -ay" to the end of the /usr/share/initramfs-tools/scripts/local-top/dmraid as suggested in https://bugs.launchpad.net/ubuntu/+source/dmraid/+bug/247027/comments/21

But I'm guessing there's a more sophisticated procedure that's not kicking in on my system. What information can I start providing to help get this fixed? (If there's a ubuntu developer interested, I can provide access directly to the box via the ilo device.)

linux-image-3.5.0-36-generic #57 precise1 (amd64)
