I have successfully built the tree from http://www.kernel.org/pub/scm/linux/kernel/git/kyle/ubuntu-dapper- updates.git but it is lacking the last commit (816aa907b909177bdf6e6e6b0d00c5e5a6e2be8c) which introduce raid support in mptsas.
Applying my backported patch (http://librarian.launchpad.net/5702451/linux-2.6.git- 816aa907b909177bdf6e6e6b0d00c5e5a6e2be8c-backported.patch) on top of it does the trick. -- fusion mpt sas driver does not find a RAID1 disk during installation(Sun Galaxy X4200 and X4100, Dell SASR5/i) https://launchpad.net/bugs/37452 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
