I'm configuring an APU2 (2 GB RAM, 3 ports) with OpenWRT 20.02.0. I have updated to the latest mainline firmware and have had some stability issues. I have turned off core performance boost. After being up for a few hours, I received the following MCE message:
[52613.653011] mce: [Hardware Error]: Machine check events logged
[52613.653022] mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 1: 9400000000000151

I am running the system off of an mSATA drive. The system has passed a full memory test.
Does this mean I definitely have a system board issue or could it be some other problem? It threw this one error over the course of a day and the system did not crash.
