Yes, but without updated kernel... so I guess I was really running at 1.35V with DLL off (if the kernel lowered the voltage).
I need to test that.
One thing to notice: I didn't have ANY issues with rebooting. It booted fine every time I tried, no failure, regardless how warm it was.
If U-Boot starts with 1.5V, then hardware levelling is done with 1.5V, right? The kernel switches to 1.35V after that... maybe that's the trick?
I'll try with various boards and combinations!

Tony, as it worked for you with either 1.39V (or was it 1.42V?) OR DLL off, maybe both have a positive effect?
What about a build with 1.39V with DLL off?
Could you please provide a build with that?
Sounds like you got that from notaz already, see my other reply though for things to test.
Regards,
Tony
