Based on the logs from successful boots, I see it's CPUFreq that gets probed after fan53555-reg. I also see that it warns about unlisted OPPs in the successful boots. I guess, the undefined instruction could occur if there's issue with CPU DVFS(under voltage or frequency that's not supported). I don't have much knowledge on the platform, I am just guessing on the possible cause here.
Yeah, that was my guess - either an out of spec voltage/frequency was selected or the regulator isn't able to keep up with the voltage transition or a load spike and the power browns out.
