Re: Fedora21/22 grub doesn't recognize my raid1/LVM partitions

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.
The exact wording of the message is:
'Unexpected system error. The system has encountered a problem and recovered.'
Does this same kernel call trace happen with Fedora 21's
installer? Or
does it fail for a different reason?
With the F21 installer, there is no error message, and the installer
does find the raid1 array. But it finds it only as one ~ 460 GB
'physical volume'; my existing LVM partitions are not recognized, so
I can't install into them.
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.

Alas, rolling my own workstation installer is beyond my present skill
level. I must decide whether to wait for Fedora 23, or to back up
everything and let the F22 installer have a crack at creating a new
raid1 array with LVMs on top of it.
Thanks again for the help,
