I'm pulling out my hair trying to figure this out...I have an issue running powertop --auto-tune where it would freeze my entire system. I tried resetting my bios and install a fresh version of Unraid - after I run the basic steps in the original post, the server still freezes. I even removed all drives/usb devices/drives, except the Unraid usb. I'm going crazy trying to figure this out. I just wanted to be able to run powertop autotune with no issues and then start tweaking the bios to get the power consumption down.
Asus WS W680M-ACE SE
Intel Core i5-12400
32GB Kingston ECC
Sometimes it doesn't freeze and I get this error:
