Comment 20 for bug 546091

John Morrissey (jwm) wrote :

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:
