Here are the steps thay will help us to diagnose what may be wrong, please
follow them:
1. Boot into you working kernel configuration
2. Please make sure you deleted /etc/X11/xorg.conf - we are not using this file
unless you are using proprietary drivers.
3. Boot into your NOT working configuration
4. Allow it to run for 5 mins
5. Reset your running system
6. Boot into your WORKING kernel configuration
7. Log in as root
8. type in konsole journalctl -b -1 > broken_boot_log
9. Attach file broken_boot_log here</pre>
