Adding some more info that I had written down for one of our community members:
Hello Jakub
Here is the response to your questions.
Q: Do you observe same behavior of console with f21/f22?
Install gets stuck at the same place: (Attached SCSI) in f21/f22 but rescue shell does NOT freeze in f21/f22.
Q: What do you use to obtain console(ipmi sol, physical connection,Š)?
‹Physical connection: Serial USB cable attached to debug port on server.
Q: What are you using as installation source(DVD, PXE, USB, remote repo,....) and what image are you using(netinst/dvd)?
‹ Installation source is a Fedora 23 DVD content put on a USB stick.
Q: Are disks already partitioned or are empty?
‹ Disks where previously partitioned (I had powerkvm installed on there) but this error occurs before I can get to the partition screen.
Q: Have you been successful with booting/installing any other linux distribution(either LE/BE)?
‹ Yes Ubuntu 14.04 / 14.10 (PPC64LE) installed smoothly. With Ubuntu 15.04 install I ran into this install error on partitioning Avago raid:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475166
However we are working around that bug by setting max_sectors of Megaraid module manually and thus able to finish the install.
We are also able to install powerKVM (IBM¹s PPC64LE KVM)
