[Bug 546091] Re: 10.04 Installer doesn't properly detect 9240 MegaRaid SAS Controlers

[Roberto Suarez]

We've got a workaround for this, though it's hard work and is not viable
as an alternative. It's just for urgent installations (as was ours). I
put it here just in case someone else wants to do as we did.

We downloaded the Live CD of Maverick Meerkat and used that to boot. The
kernel in Maverick (2.6.34-something) detects correctly the disks. We
launched a terminal and partitioned our target system, mounting the
target installation under /mnt/target. Then we debootstrapped Lucid into
it, like this:

debootstrap lucid /mnt/target

(a local mirror or proxy helps a lot, especially if you're making
several installations)

Then we chrooted into /mnt/target (mounting previously /dev and /proc)
and did this:

apt-get install python-software-properties
add-apt-repository ppa:kernel-ppa
apt-get update
apt-get install linux-image-2.6.34-5-server

(there's a linux-image-2.6.35-something available, but we used 2.6.34
because it's supposed to be the stable release)

This also pulled and installed grub, but YMMV. We also installed lvm2
because that's what we used for the system, but depends on your setup.
Note that we didn't use any Maverick packages: the kernel-ppa repository
has kernels for Lucid, even if newer than the ones in the release.

After that, we changed the chroot's root password (or you'll have a nice
bootable system that you can't log into :-)) and rebooted. The system
booted with Lucid and kernel 2.6.34, detecting the RAID perfectly.
