Both are worked in PR1.0-PR1.1. But in PR1.2 sr_vdd2_autocomp was disabled in kernel because it seemed as a source of hardware failure.

Now we can set both to 1 again and it works for me around 24h well.

BTW, from comments it looks like Nokia set sr_vdd1_autocomp by default but I am too lazy to do a reboot to check that - can you do?

I would be not surprised if power-saving discussed here can be accounted to sr_vdd1_autocomp.
