Thanks for all the testing. So it sounds like this bug was introduced in the 3.13 kernel. In order to bisect, we need to narrow down further and identify which v3.13 release candidate introduced the regression.
However, it might be good to first test the latest mainline kernel to see if this has already been fixed upstream. The latest mainline kernel is v3.14-rc1, and can be downloaded from: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc1-trusty/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1276705 Title: Kernel 3.13 fail to boot with LSI SAS1068E (Dell SAS 6/iR) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1276705/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
