[SOLVED]Fail to activate /dev/zram0 when booting

Hi,

I configured zram exactly following the wiki. When I boot the system, the console outputs 

 Fail to activate /dev/zram0 
 Denpendencies failed for swaps

I use swapfile and zram at the same time.
What should I do resolve it?

Post more context. The actual system journal and also check "lsmod | grep zram"
