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

[John Morrissey]

The megaraid_sas driver in the current linux-2.6 (stable) git tree has
support for this adapter, the LSI SAS2 "SKINNY." I've cherrypicked the
updated driver into the latest Lucid kernel and uploaded to this PPA:

https://launchpad.net/~jwm/+archive/lp546091

(Note that the built kernel is based on the next Lucid kernel update,
2.6.32-24.42. Currently, the only difference between .42 and .41 are
some fixes in the i915 graphics driver.)

I'll try to keep the PPA kernel up-to-date, but I can't make any
guarantees.

Also, I'm netbooting to install, so I'm adding the newer scsi-modules
udeb to the initrd like so:

[jwm at boost:pts/1 ~> wget -q http://us.archive.ubuntu.com/ubuntu/dists/lucid-updates/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/initrd.gz
