So there's the kernel bug, 1225671, that ends up stopping the arrays,
but then there's a misleading message saying there's a problem that's
been corrected, yet clearly not corrected.

Does this same kernel call trace happen with Fedora 21's installer? Or
does it fail for a different reason?

There is a beta release criteria for this:

Hardware and firmware RAID
The installer must be able to detect and install to hardware or
firmware RAID storage devices.

And there are test cases, and there's an entry for software raid in
the test matrix. So it should get tested multiple times per build, and
there will be a dozen builds pre-alpha, pre-beta, and pre-final. So
it's a bit surprising this is so easy to hit (the bug report has
someone hitting it in virtual box).

Obviously this can't be fixed with official media, you could roll your
own workstation installer compose and instead use kernel 4.0.5 which
should fix this bug, and then you'd be able to install F22 to this
existing software raid.
