I have an install with raid1 /boot and raid0 /. Rescue mode loads all the raid modules but is unable to find a Fedora file system. Nothing really in /tmp/anaconda.log about this.
We need to switch away from using raid autorun anyway...

The rescue mode in today's F7t4 candidate tree finds my RAID1 / just fine. Do you still have your system available to retest this?
The Pogo amd64 box in my cube can do mdraid and that was my test case. However I'm not in my office until May. Perhaps somebody in the BOS office could be convinced to verify there, but if it is working for you now, perhaps this is fixed.
Yeah, I can't reproduce this at all anymore. Marking as fixed.
