I am sure the issue is not about RPI's lack of ability to power itself down. 1. there is no code for the arm to poweroff. 2. the cpu_reboot code in src/sys/arch/arm/arm32/arm32_reboot.c in 1.6 which is the revision in netbsd-7 reboots on halt.

(Already happened once, with the device going to file system checks.) Now, when I use the device in headless manner, I have difficulty deciding exact time of pulling the chord to safely poweroff the device. Is there any way out of this?
