crash during system upgrade

I tried to fix crash at last full system update.
Firstly I verified and reinstalled modules at the system update. I found linux-firmware and linux have problem and reinstalled both. After reinstall, linux-firmware seems to be fixed but linux has still errors. As I noticed other module seems to have problems, I think my system is not clean. Anyway, the first problem missing nvidia firmware is cleared so I reboot system. First thing is remove nvidia package and use nouveau as driver.

log

• make new archiso archlinux-2016.10.01-dual.iso
• arch-chroot
• switch to nouveau
  
  • install nouveau and mesa-libgl pacman -S --needed xf86-video-nouveau mesa-libgl
  • remove nvidia pacman -R nvidia
  • also remove nvidia-utils pacman -R nvidia-utils
  • added nouveau in /etc/mkinitcpio.conf
  • regenerage initramfs mkinitcpio -p linux
• reboot
  it seems nouveau driver loaded successfully and login screen show up but it’s same as nvidia driver case, it freeze and I can do nothing other than force shutdown.

So verify and reinstall last upgraded packages didn’t solve problem.
Next I should try is this
https://wiki.archlinux.org/index.php/pacman#pacman_crashes_during_an_upgrade

The procedures

1. Boot using Arch installation media. Preferably use a recent media so that the pacman version match / is newer than the system.
2. Mount the system’s root filesystem mount /dev/sdx /mnt as root, and check the mount has sufficient space with df -h
3. If the system uses default database and directory locations, you can now update the system’s pacman database and upgrade it via
   pacman --root /mnt --cachedir=/mnt/var/pacman/pkg -Syyu
   as root.
4. After the upgrade, one way to double-check for not upgraded but still broken packages: find /mnt/usr/lib -size 0
5. Followed by reinstall of any still broken package via
   pacman --root /mnt --cachedir=/mnt/var/pacman/pkg -S package

Tried this but not solved I think.
The problem is my system missing some system files. How to find those files and owner of those packages?
this post hinted me. Just pacman -Qkk verify all packages.

rm conflict files empty not owned by any packages and reinstall.
