F23 Server - "Unknown Error" During Installation - DeviceTreeError?

Background: I'm totally new to linux and my end goal is to get an Amahi 9 based home server setup (which requires Fedora 23 Server to be installed first). I had previous success with an older set of hardware that I used as a trial run before investing in new hardware and additional storage. The new hardware setup consists of an AMD A88X based system (Asrock FM2A88M +Pro3 and AMD APU) and I re-used 2 of the old SATA hard drives by pairing them up with the UEFI AMD hardware RAID (1) process.

To make sure the RAID drives were set up correctly, I mock-installed Windows 10 up to the point of choosing a hard drive location. After using a separate USB flash drive to load the AMD RAID drivers, everything appeared to work fine.

Which brings me to the F23 Server installation process. With the hard drives plugged in, the installation process crashes right after the language menu GUI pops up indicating an "Unknown Error" has occurred. I tried out the bug submittal process:

reason: blivet.errors.DeviceTreeError: failed to add slave viaccbhhiciad of device viaccbhhiciad1

What does that mean? Not sure how to troubleshoot at this point. I tried both the UEFI and BIOS boot versions of my Fedora Media Writer based flash drive. I tried both the Net Install and full versions of the F23 Server ISO.

I would not install a non-supported version of Fedora server! Fedora 23 is End-of-Life since Dec 2016 and not supplied with important security updates anymore.

Please try installing a supported release (currently F24 and F25).

If you are looking for something stable without the need for regular upgrades, you may want to consider CentOS with 10 year support.

Follow-on: I found the root cause of the problem. The 2 old drives were previously setup in a RAID configuration on the old motherboard. Somehow it carried that information over to the new setup and made a mess of trying to setup the AMD RAID. I used a Windows10 install disk (USB flash) to run 'diskpart' to clear out the old information before trying again to create a new array.

Good news: It appeared to work and I no longer get the fatal error from the installation GUI.

Bad news: The installation GUI appears to recognize both drives as independent entities (sda1 & sdb1)

(Mostly just a learning exercise at this point as I'm going to remove the array and go back to AHCI to continue installation. The general consensus from the Internet appears to be that unless you've got an expensive add-on RAID controller, using virtual RAID by way of motherboard firmware or OS software is a bit of a crapshoot anyway.)

Please try a more recent version of Fedora. Fedora 23 is out of support, how about trying Fedora 25?

If this bug is still present with Fedora 25, please have a look at .

Thank you all for the prompt replies. Unfortunately I'm tied to Fedora 23 for now as I'd like to continue to use Amahi (and the current release depends on having F23 installed). Rather than continue to fight this battle, it looks like if I disable the AMD RAID functionality and instead rely on the AHCI configuration for the hard drives, the installer starts up without a hitch.

Looks like I'll have to come up with a different storage scheme to work around the lack of RAID for now.

If you want to use outdated software, you should use Debian or RHEL/CentOS instead. This way you'd get at least some updates for critical bugs or security issues. Running an unsupported version of any kind of distro or network-related software on a network is irresponsible.
