@schunckt I have disabled patch/kernel/archive/sunxi-6.1/patches.megous/media-sun6i-csi-Pass-on-g_parm-s_parm-to-the-subdev.patch as that was the code causing the kernel oops. You should be able to use the camera now with 6.1 kernel as well 

Alright. some progress on testing.
 
Tried rtcwake command, that gave me a write error I will see what caused this later. My board doesn't have hdmi, so hdmi-cec is out of picture. That leaves me with IR, but the board doesn't have inbuilt IR receiver, but has some gpio pin to interface one. I didn't had an IR receiver so have ordered it and it will likely arrive by Monday.
 
Meanwhile, I enabled DEBUG_MONITOR in the crust config and used that for testing. This gave me access to debug terminal for crust when linux is suspended or powered off.
I ran systemctl suspend that stopped linux and dropped me to crust debug console. I pressed w on the crust debug console and it brought back linux from suspended state. I powered off Linux and that too dropped me off to crust debug console. I pressed w and it rebooted the board. So I guess its working the way it was expected.
 
I will also test if the system resumes on IR once that arrives and will try to debug why rtcwake command is not working.

I have also noticed this issue on nanopi duo2. I tried to find out the cause of it and I think its caused by this upstream commit. I added a revert patch in userpatches/kernel/archive/sunxi-6.1 and compiled an image. Image was able to boot successfully. I am going to investigate a bit more about why its impacting 32bit allwinner boards, and will raise a merge request with the fix once I have it ready
