I have a custom board based on imx6 dual. I'm updating to BSP 4.9.11 and I have a problem with the reboot. I'm using sysvinit and the command:
# shutdown.sysvinit -r 0
does a shutdown but the board don't reboot. The same step in my current BSP 3.14.52 based, is working ok. Something in the kernel to check?
