Ok, I did try to minimize config differences. I'm still booting from
NOLO. Now I'm doing the tests from init=... boot. idlest1_core
blocking bits says 0042. But the LEDs still don't blink.

I made config with pretty minimal differences from defconfig (making
required drivers =y, lockdep off so that video works).

Do you think you could try with my config?

Yes, I'm doing this, on console.

Thanks and best regards,
