The problem this bug report is about is "boot delay and udev/mdadm (raid) disturbance". As such, it is a duplicate of #942106.
Then the bug report offers an explanation and a solution. The MD autodetection only occurs when md drivers are statically compiled (see https://www.kernel.org/doc/Documentation/md.txt). The Ubuntu MD drivers are compiled as mdules, so will not be automatically detected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/551719 Title: MD_AUTODETECT=y kernel option is obsolete (boot delay and udev/mdadm (raid) disturbance) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/551719/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
