Comment 1 for bug 157648

Does my case look similar?

I've installed 7.10 amd64 on a Intel Server System 1500 with 2 SAS drives, which unfortunately has a SW raid system incompatible with open OS', so I'm trying to use Linux mdadm. The first partition on both drives was created and marked as bootable, and raid autodetect. The installation goes well and the system boots ok on /dev/md0, and /proc/mdstat and mdadm -D show everything's in sync. After shutting down the system and unplugging one of the drives -- it doesn't matter which -- the systems waits for 2-3 minutes at the "loading, please wait' prompt, then spits out some errors like "stdin: error 0" and then the output similar to what happens when you run modprobe with no arguments, and some more "no such file or directory" regarding parts under the root fs (like /dev/ /sys/ /proc etc.), eventually dropping into a busybox shell.

I also tried running this on both drives, with no effect whatsoever.
