Comment 26 for bug 539324

I'm encountering this same issue with the 10.10 Alternate installer (amd64). In my case, I'm trying to install to existing encrypted lvms on an existing RAID5. The installer can't seem to handle the RAID either ( I have to assemble myself from the shell). It also fails to unlock ( I have to do it via cryptsetup from the shell). However, I can install via the no-swap workaround described above just fine...so no issues with the RAID or crypt once I unlock them manually....just something about mounting that swap apparently....
