I may have a better answer for you now. In the intervening time period, I've discovered a potentially-relevant bug, involving interactions between the kernel power-domain driver and ATF. See this series for my current fixes: https://lore.kernel.org/linux-rockchip/20220406014842.2771799-1-briannorris@chromium.org/ [RFC PATCH 0/2] rockchip / devfreq: Coordinate DRAM controller resources between ATF and kernel If that happens to help you (it may help, for instance, if your system was toggling NPLL off/on like mine was; it also may help if you're hitting a race on PMU_BUS_IDLE_REQ like noticed in patch 1), I'd love your feedback there. It's still possible your problems are completely unrelated though. Regards, Brian
