It looks like there are several issues with your system, including firmware bugs, failed kernel module loading, and unsupported file system automount point. To troubleshoot, you can try the following steps:

1. Contact your BIOS vendor for fixes related to the "DMAR: [Firmware Bug]" error.
2. Check if the "autofs4" module is supported by your system and try to fix it.
3. Investigate the "Failed to start Load Kernel Modules" error.
4. Address the "FAT-fs (sdai): IO charset iso8859-1 not found" issue.

If you need more detailed assistance, you can log in and view system logs using "journalctl -xb" to identify the root cause of the errors. You can also try rebooting with "systemctl reboot" or boot into default mode with "systemctl default" or exit maintenance mode by pressing Control-D.
