Can't reboot Intel Atom x5-Z8350 running Ubuntu Server 20.04/21.10 – kernel soft lockup

I'm unable to completely shutdown my system after running sudo init 6 or sudo shutdown -reboot This is the system I have, which runs on the Atom x5-Z8350 Cherry Trail CPU.  Previously I installed 20.04 I saw an error while rebooting – part of that error was: > an error BUG: soft lockup - CPU#1 stuck for 22s! Unfortunately I'm not sure where I could have found the entire log file, and now I've installed 21.10. I thought the kernel on 21.10 would have solved my issue.  Things looked well since the verbose was giving me back "[ok]" for everything.  Unfortunately, there were no errors shown on the display, and my display turns off but the system and keyboard stay on, and I'm forced to hold the shutdown button. What commands should I run that could help you guys better understand my hardware plus how can I log or find the logs for the failed reboot? AFAIK errors for reboot/shutdown are not saved since the system dismounts.
