Had a good working F14, did a fresh install of F16, right after I set the partition options (/ sda5 and format ext4, /home sda6 no format) click next and errors out. I've rebooted and tried again, same results. I can reinstall F14 no issues. I tried loading F15 just for kicks, but it fails same point as F16.

The error log is 24 thousand lines long, so I'm not going to copy all of it, but here's the beginning 20 lines and ending 5 lines. Let me know if I should provide more info

Usually during the installation if you press ALT+CTRL+F[0-8] you can view different consoles with installer output, syslog and access a shell. Gathering information may help tracking down the issue. Without it all that remains is guesswork because there's no way telling why it doesn't 'swapon /dev/sda2' and what lead up to it. Retrying the installation, saving as much information to an USB stick (or rsyslog server?) as possible, Pastebin the log, providing full 'fdisk -l' output plus hardware specs may help.

I tried to delete SDA2, the swap partition and recreate it, unsuccessfully. I tried to make it the same size as the original, and smaller, always in the same location. Every time it gave an error saying something like the swap needed to be on 1 hard drive and select from the allowed drives. After trying several different things I decided to build without a swap partition. The install went smoothly after that. So now I just need to create a swap partition.
