I don't know why it restarted but the priority of your new swap will be lower than the default swap and thus it will get used only when the 768 emmc swap fills. To enable it with higher priority you either need to use swapon from easydebian or Code: swapon /dev/swap1.img swapoff /dev/mmcblk0p3; swapon /dev/mmcblk0p3
swapon /dev/swap1.img swapoff /dev/mmcblk0p3; swapon /dev/mmcblk0p3
swapon /dev/swap1.img
