So it seems some CPU scaling works on CPU0, but not on CPU1.

Maybe - I noticed that just after booting scaling_max_freq was 2534000, but it dropped down soon after. I can provide the same logs as before again and you can check them to make sure that a.) I enabled ignore_ppc properly and b.) it had the expected effect.

Can you try the following: Edit /etc/default/grub (you need to do this using root privilege) and change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.ignore_ppc=1" and then run: sudo update-grub and reboot.
