I'm running Ubuntu Server 22.04 LTS on my brand new NUC but 1-2 hrs into running it as a validator on the Ethereum testnet, it freezes. The only way to reboot it, is to hold the power button in for 10s and then to restart.
The screen is frozen where it stopped working. I have 64GB of Lexar SODIM DDR4 3200 RAM and a 2TB Crucial NVMe SSD installed. While running, it never goes above 6GB RAM usage. Also the CPU is not labouring either.
Have done a MemTest86 for 12hrs (4 passes) and no issues found - 100% pass.
What else can I try?
Thank you for posting on the Intel® communities.
Since we are working on this same unit on the original thread (https://community.intel.com/t5/Intel-NUCs/Bad-UBUNTU-SERVER-20-0-4-or-RAM/m-p/1408661#M93340), we will proceed to close this one.

Please do not close this ticket since this is the latest state of my problem with getting Ubuntu to run properly. You referred to 20.04 LTS as being the only supported version of Ubuntu Server that Intel supports for the NUC11 and you were going to get more info on that. Please revert on this ticket when you have a moment.
Thank you in advance.
