As phillip previously said there is a dm-raid456 on the way (dm-raid is the module and it exists in 2.6.38 but is still listed experimental).
I believe that most standard RAID5 arrays do work or we would see more bugs (RAID5 is a common setup with dm). Obviously yours is a special case and requires some work to get the dmraid driver working correctly. What are the errors with 11.04? Ubuntu at the end of a the day is a 'bleeding edge' distrobution, many of the new features included in it have not been tested longer than a few months and although most bugs are fixed before release some of the lesser used features can end up with regressions. You can always choose a more stable distro like debian if you are looking for ultimate stability. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/666577 Title: dmraid hangs trying to start ICH9R RAID 5 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
